Yardage format: SPEED DIAL

Laser etched large size 50 YD increments for rapid dialing in. Increments marked up to one turn of the turret. The maximum marked yardage will vary based on the cartridge.  A 200 yard zero (0) is recommended for this yardage format.

Sample knob: 200 yard zero (0) to 800 yards

Yardage format: LONG RANGE HUNTER
50yd increments marked on two tiers which represents two turns of the turret. Calibrated out to 1000yds for most Magnum cartridges and approximately 800yds for standard cartridges.

Sample knob: 200 yard zero (0) to 1000 yards

Yardage format: MILITARY
Retains factory type MOA scale at the bottom of the turret. 50yd increments marked above the scale at the required amount of MOA.

Sample knob: 100 yard zero (0) to 1200 yards.

Yardage format:WINDAGE
Custom windage turret to match your bullet’s wind drift. Marked in 100yd increments for a right or left 10 MPH crosswind. Instructions provided for adjusting crosswind speeds.

Use the factory target turret to adjust bullet impact until you are sighted in (zeroed) at 100 or 200 yards. Remove the factory target turret and mount the Custom Turret setting it at your 100 or 200 yard zero (0). Laser range find the distance to your target. Starting at zero (0), dial past each consecutive increasing yardage increment (200, 250, 300, etc.) until you dial in your target distance.

You also have the ability to fine tune the yardage setting. Between any two consecutive 50 yard increments, there is a series of vertical click lines. The halfway point between consecutive 50 yard increments would be a 25 yd setting. You can further split the difference and dial in a shot down to the 10 or even 5 yard increment depending on the distance.

LONG RANGE HUNTER & MILITARY multi-tier yardage formats: For shots past one revolution or zero (0), you will visually transition from the last yardage increment in the first row or tier up to the next consecutive yardage increment within the second row or tier. Continue dialing past each consecutive yardage increment along the second row until you dial in the required yardage or transition up to the next row of yardage increments.

EXAMPLE: You are dialed in at a 100 yard zero (0) and our target appears at 800 yds. Dial past each consecutive increasing yardage increment (ie. 200, 250, 300, etc.) until you dial in 800 yds. Conversely, if you were dialed in at 800 yds and wanted to return to the 100 yard zero (0), dial past each consecutive decreasing yardage increment (750, 700, 650, etc.) until you are at the 100 yard zero.

1. Select the bullet caliber from the dropdown box.  The list of available bullet manufacturers for that caliber will show up in the manufacturer drop down.

2. Select your particular bullet and associated B.C.

3. Type in your chronographed velocity in the optional Velocity Box .

Absolutely!  Just click the field data tab on the order form to reveal that field data input window.

The field data must be complete in 50 or 100 yard increments out to your furthest intended distance. You can provide us the dial-up in clicks and we will make you a turret with the data provided.

Only the data you give us will be provided.  We will not extrapolate missing drops!

You may still contact us directly to give us your data by phone if you wish.

The price for this custom turret is the same as the standard turret for factory ammo or handloads.

Your BDC product will work regardless of the altitude for short to medium ranges.

For long range hunting, you need to determine an approximate 4000 foot bracket of altitude.

Example: Hunts between 5000-9000ft. above sea level, select 7000ft. as an average.

Our Turret Adjustment Calculator is the perfect tool to adjust your turret to varying bullet weights and types as well as changing field conditions. For more information, visit the Turret Adjustment Calculator at the top under "Other Products".

Most scopes provide lines that reveal themselves after a full revolution of the turret.  If you have a scope like this, sight-in/zero your rifle dead on at 100 or 200 yds. Black out all the visible horizontal lines on the elevation shaft except the line directly below the bottom edge of your BDC product.

Starting at your 100 or 200 yd zero (0), one visible horizontal line equals the 1st tier (1st turn) of yardage increments. One full revolution of the turret will reveal a 2nd horizontal line which indicates the starting point of the 2nd tier (2nd turn).

At any point during shooting, by counting the visible horizontal lines on the elevation shaft, you can confirm which tier of yardage the turret is currently on. Turning the turret to the zero (0) will set the turret at the starting point of the tier.

The following riflescopes have been tested by Kenton Industries’ staff or associates and are recommended as an overall good value.
Simply remove the factory target turret and replace it with Custom Turret or Ballistic Strip.

No, installation requires only loosening the setscrews (or vertical top screw) on the factory turret pulling it off the elevation shaft and replacing it with your Custom Turret.

If you have a Zeiss scope with hunter turrets and would like to order target turrets, we can retrofit your Zeiss scope with a Custom Turret or a standard factory target turret.  Please send your Zeiss scope to:

Custom Turrets can be calibrated for all values of click adjustment. Your scope’s adjustment is not altered but the yardage increments are marked at the required number of clicks of adjustment based on your bullet’s trajectory. Not only will you be able to rapidly dial in any range in 50 or 100 yd increments, but you have a series of vertical “click” lines in between each set of consecutive yardage increments giving you the ability to dial in a shot down to a 25, 10, or even 5 yd increment depending on the target distance.

You should always re-zero a rifle when time and conditions permit. However, if you follow the recommended advice, you may only have to re-zero your rifle one more time.

For example, your rifle is currently zeroed for your home range (1000ft. above sea level @ 70° F). Make sure that you are dialed in at 100 yds and remove your low altitude calibrated Custom Turret. Mount the one calibrated for high altitude setting it at 100yds. Shoot your rifle at a target placed at 100yds when you are at or close to the 7000 ft. altitude.

Example: You determine that the center of your 3-5 shot group is now 2 in. higher at 100yds. Rotate the knob two clicks (@1/4 in. per click) down (decrease yardage). Loosen the setscrews, reset your Custom Turret to 100yds, and then tighten down the setscrews. Now you are zeroed for the hunt with the properly calibrated Custom Turret. Custom Turret swapping is always done dialed in at 100yds regardless of your zero range.

At the end of the hunt or when you get home you simply remount your low altitude turret setting it at 100 yds, add two clicks (increase yardage), loosen set screws and reset turret to 100yds.

By recording the required adjustment in a logbook or taping the data on the stock of the rifle you will never have to re-zero your rifle again. You will be able to continuously mount and remount different turrets.

Your logbook entry might read: 100yd zero @ 7000 ft = 2 in. high.

You might not even have to re-zero the rifle at 100yds, but simply switch turrets. If you are shooting a high velocity magnum cartridge, the altitude and/or temperature change will probably not have a significant enough effect on the trajectory of your bullet due to the short flight time out to the first 100yds.

If the changing field conditions did effect your 100yd zero with the center of your 3-5 shot group ﾽ in. higher, this change would place your shot only 2.5 inches higher at 500 yds. The kill zone area runs 16 to 24 inches depending on the size of the game animal. You may consider keeping it simple and just swapping turrets.

If your scope has 1 moa adjustment (1.047 inches of bullet impact change per click at 100yds), your click adjustment value might be greater than the actual bullet impact change at 100yds.

The size of your target and the distance you intend to shoot will determine how precise you need your 100 yd zero to be. The smaller the target and the farther the shot the more precise you have to be.

If the gunpowder used in your cartridge is extremely temperature sensitive you may loose enough muzzle velocity at extreme cold temperatures to substantially effect bullet impact at 100yds.

Because of a broad range of variables: the amount of increase in altitude, the drop in temperature, and your gunpowder’s sensitivity to temperature change which alters your cartridge’s muzzle velocity, it is best to re-zero your rifle the first time you are swapping turrets and record the results so it will be the last time!

You can shoot bullets of the same weight if those bullets are of the same general type.  For example; If you are shooting polymer ballistic tip bullets of the same weight from two different manufacturers generally you will notice only a slight variation in point of impact if the ballistic coefficients are similar.

If however you wish to shoot flat points and BTHP’s of the same weight expect to see differences in impact as each of these bullets have substantially different ballistic coefficients.

Our Turret Adjustment Calculator is the perfect tool to adjust your turret to varying bullet weights and types as well as changing field conditions. For more information, visit the Turret Adjustment Calculator at the top under "Other Products".

Alternatively, you can purchase a Custom Turret that is calibrated for your main load and adjust the turret for the other loads. For example, your turret was calibrated for the 308-168gr. Federal Match load and you want to also shoot your 150gr. Federal NBT load. You will have to subtract a set amount of clicks from each 50/100 yd setting. A 500 yard shot for the 150 gr. NBT would be to dial the turret to 500 yds then subtract (decrease yardage) 9 clicks. You can make up a simple chart for the 150gr. load: 100 yds -2 (clicks), 200 – 3, 300 – 4, 350 – 5, 400 – 6, 450 – 7, 500 – 9, etcﾅ

The preferred way is to have a second turret calibrated for the 150gr. load. This way you can swap knobs accordingly. You should keep a simple log that tells you how many clicks to subtract to re-zero the scope from the 168gr. 100yd zero to the 150gr. 100yd zero. For Example: Log entry: 150gr. 100yd zero = – 2 clicks down @ 100yds. (mount 150gr. turret and set at 100yds; – 2 clicks down, loosen setscrews, reset knob to 100yds, then tighten setscrews.)

Now you are ready to dial in and shoot the 150gr. load. The process would be reversed when you want to remount your Custom Turret calibrated for the 168gr. load. (mount 168gr. turret, set at 100yds, +2 clicks up, loosen setscrews, reset turret to 100yds, then tighted setscrews).

How many times have you missed an important shot because you didn’t think there was a strong enough crosswind to even bother compensating for? How about when you moved your crosshair to compensate for the crosswind but ended up with a wounded animal or a miss, because you adjusted incorrectly.

Improper adjustment for crosswind at medium ranges, will result in poor bullet placement and wound the game or depending on the crosswind speed, quite possibly miss completely! If there is no adjustment made for long-range shots even for a mild crosswind the shot will likely be a complete miss.

The Custom Windage Turret was designed to give the shooter a fast and easy way of adjusting whenever possible for every shot that requires crosswind compensation. The Custom Windage Turret is adjustable for a wide range of crosswind speeds and any angle of crosswind.

The Custom Windage Turret will get you in the habit of compensating for crosswind making you more proficient.

Thank You for purchasing your Kenton Industries Custom Windage Dial. These simple instructions will help you better understand the proper use of the turret for target or hunting applications.  Your turret will be marked similar to the one shown in Figure 1.

This is an example of a Custom Windage Turret (1/4 MOA clicks) calibrated for a .308Win 175 gr. HPBT Match Bullet; 100 yard zero, Right or Left 10mph crosswind compensation out to 100yards:

In this example, if your target is 300 yards away, with a 10mph 90 degree crosswind blowing you would turn the turret until the “300” lined up with the indicator on the scope body and you would be corrected for windage at that distance. You correct right of left depending upon which direction the wind is crossing your target.

Your turret is calibrated for a 10 mph crosswind.  But you can use the turret under differing wind condition with equal success. Simple math can be used to correct for a difference in wind speeds.  For instance, if the wind is blowing at 5mph you simply half the distance to 150yards, because 5mph is half of 10mph.  Likewise if the wind is blowing at 20mph you would double the distance to 600 yards, because 20mph is double 10mph.

 This can be done for any wind speed.  If a 7mph wind is blowing, this is 70% of 10mph, so you would dial 70% of 300, which is 210 yards (300x .70 = 210 yards.)  If a 12mph wind is blowing this 120% or 10mph, so you would dial 120% of 300, which is 360yards (300 x 1.2 = 360yards)

 What about changes in Wind direction?

If the wind is not blowing at a 90 degree angle its affect on the bullet will be less depending upon the actual angle of the wind with respect to you and the target. Again we can use a bit of simple trigonometry and math to make a correction for the crosswind component. The effective crosswind component is the sine of the angle times the actual wind speed.  Refer to Figure 2

Fortunately, the math is relatively easy for the most common angles.

The Sine of 30 degrees is .500

The Sine of 45 degrees is .707

The Sine of 60 degrees is .866

The Sine of 90 degrees is 1.00

For a 10mph wind blowing 30 degrees off your Right shoulder  and  across the target 300 yards away, the correction would be  sin30 x 10mph  = .5×10 = 5mph.  5mph is half of 10mph so correct for ½ of 300 yards or dial to 150yards right correction

For a 10mph wind blowing 45 degrees from your left and across the target 300 yards away, the correction would be sin45 x 10mph = .707 x 10 = 7mph.  This is 70% of 10mph, so you would dial 70% of 300, which is 210 yards left correction (300x .70 = 210 yards.)

For a 10mph wind blowing 60 degrees from your left and across the target 300 yards away, the correction would be sin60 x 10mph = .866 x 10 ~ 9mph.  This is 90% of 10mph, so you would dial 90% of 300, which is 270 yards left correction (300x .90 = 270 yards.)

Putting it all together!

With the basic tools in place we can now dial in the appropriate yardage for any wind speed and direction.

Your target is 400 yards away; the wind is blowing 6 mph, from 30 degrees over your left shoulder.  What correction do you make?

The sine of 30 degrees is .500 so .5 x 6mph = 3mph.  3mph is 30% of 10mph, so 30% of 400yards is 120 yards. (400x .30 =120) You would adjust your Custom Windage Turret to 120 yards left correction.

One last example;

Your target is 275 yards away; you have a wind blowing 45 degrees into you from the right at 14mph. What correction do you make?

The sine of 45 degrees is .707 so .707 x 14 ~ 10mph. Your turret is calibrated for 10mph so just turn the turret to 275 yards right correction!

At Kenton Industries, we are confident our custom bullet drop compensator (BDC) turrets, strips, and charts are far superior to generic “one size fits all” BDC reticles.

A generic “one size fits all” (or even a choice of a non-magnum & magnum) BDC reticle can only be set at one specific muzzle velocity, calibrated for one bullet weight and type, and generally is set for an altitude of 0ft. above sea level @ 59 degrees (F).

You must ask the following questions if you are thinking about purchasing a scope with a generic BDC reticle:

1. How close is my muzzle velocity to the muzzle velocity setting?
Non magnum muzzle velocity can range from 2400-2800 fps. Magnum muzzle velocity can
range from 2800 to 3500 fps.

2. Is my bullet the same weight and equally important the same type?
A .30 cal 180gr soft point bullet will bleed off velocity at a much faster rate than a .30 cal 180gr hollow point bullet producing a steeper trajectory.

3. Is my hunting/shooting altitude at 0ft. above sea level @ 59 degrees (F)?
Shots taken over 2000ft. ASL will hit high on the target and hit out of the kill zone (or fly over the target) at high altitudes.

4. Is my preferred sight-in/zero range (ie. 100, 200, 250,or 300 yards) offered?

CUSTOM TURRET/STRIP/CHART:
A Custom Turret/Strip/Chart is like a fine tailored suit. It is calibrated for your cartridge, specific muzzle velocity, exact bullet weight & type, and is set at an altitude & temperature which best fits your hunting needs. Also, you get to decide if you want a 100, 200, 250 or 300 yard sight-in/zero range.

BENEFITS OF USING A CUSTOM TURRET OVER BDC RETICLE:
1. Calibrated to your specific load and hunting conditions providing custom bullet trajectory to the target.

2. Capability to dial in the yardage increment indicated on your laser range finder.

3. Your shot is taken using a basic crosshair (in the center of the optic) which provides a clear view, precise target alignment point, and covers up very little of the target.

4. Flexibility to move Custom Turret to another riflescope or purchase another Custom Turret for new load, bullet wt. or type, etc. (Unlike the permanent etching on a reticle with no way to change the trajectory).

Utilizing Mil Dots as aiming points, that is the “Dots” of the mil dot system, requires knowing which Dot to use for each 50/100 yd increment for the entire trajectory of your bullet. The Dots designated for long range will have to be the aiming point for a series of yardage increments. The amount of hold from target center will be different for each increment depending on the distance. You may have to hold the designated Dot low from target center for one 50 yd increment, then high for the next 50 yds. There is no consistent pattern to go by. Each high and low hold from target center will range anywhere from several inches to a few feet depending on the distance. For some long-range shots, you will have to place the appropriate Dot literally above or below your target for the proper bullet drop compensation. This provides no real aiming point to focus on which is a crucial factor for accurate long range shooting.

The disadvantages of utilizing Mil Dots as aiming points for bullet drop compensation are as follows: The limited number of Mil Dots having to be utilized as aiming points for so many yardage increments creates the problem of so many different holds on your target. Shooting at high altitudes or extreme temperatures requires different holds than that applied for the field conditions at your home range. The size of a Dot covers up too much of your target for a precise shot at long, as well as, medium ranges. The dot completely covers up small or partially concealed targets at medium to long-range engagement. You cannot be dialed in at an appropriate yardage setting with the Mil Dot system.

The Mil Dot system should be used for what it was designed for which is range finding. However, with laser range finders becoming inexpensive, and determining target distances at (increasingly) greater ranges, Mil Dots can be categorized as a good back up source for ranging finding.

On the other hand, a Custom Turret/Strip provides you with the ability to visually dial in the range, point your crosshair at center mass of target for a clean, solid hit. You can already be dialed in at an appropriate yardage setting based on the terrain, which is simpler, faster, and more accurate than trying to select the appropriate Mil Dot and proper hold on the target.

Utilizing a Custom Turret/Strip as the means of bullet drop compensation gives you the ability to use the fine aiming point of a crosshair which covers up very little of the target. You can aim center of mass for a clean, solid hit no matter how far or how small your target is. In between each set of consecutive 50yd increments there are a series of vertical “click” lines giving you the ability to fine tune a shot down to the 25, 10, or 5 yd increment depending on the distance. Side note: You should always be dialed in to a yardage that best represents your hunting mode: stalking vs. a medium or long-range ambush position. . You cannot be dialed in when using Mil Dots.

The following formats and options are available for riflescope models which can mount a Custom Turret.

1.) Multi-tier MOA scale (no yardage)

2.) Full right and left turn MOA scale or half turn right and left scale (windage knob).

3.) Urban police sniper TTC. 25yd to 200yd scale with standard 100 yd sight-in/zero (0). (optional zero upon request).

4.) Subsonic ammunition marked in 10 or 25 yard increments.

5.) 10 MPH crosswind compensation for MilDot or MOA reticles. Compensation is marked above the 100 yd increments on your Custom Turret.

6.) +/- 30 degree shooting angle adjustment posted above yardage format (alternative angle upon request).

The above formats or options are included in standard pricing and are available upon phone call orders.

Customer’s desiring their own unique format are encouraged to call for pricing and availability.

Your Custom Turret/Strip/Chart will be correctly calibrated based upon the specific ballistic information we have received. If you find that your bullet is hitting differently than expected there are several things that can cause this.

Most commonly, the rifle may not be zeroed at the correct yardage the turret is calibrated for. A simple check of the zero range will often correct the issue.

You may be firing a different load than what the turret is calibrated for. All of our turrets are marked with the load information so you can easily distinguish the proper load for that turret.

Sometimes the scope may not track correctly. If your turret is calibrated for 1/4 click (.250 MOA) the scope may actually track slightly above or below this value. For instance if the scope tracks (.262 MOA), for every click you will be hitting higher than expected. This error will compound as you add clicks for longer ranges.

You can determine your scopes tracking by running a simple test. Zero your scope at 100 yards, then fire a nice group in the bullseye. Turn the elevation knob one full revolution up fire a nice group again. If your scope is 1/4 MOA click 15MOA/revolution, use should have a nice group centered 15.7 inches above the bullseye group. If this is not the case, your scope will track higher or lower depending upon upon the distance from group center to group center.

Divide the distance center to center by 1.047 and divide again by your total clicks per revolution. This will give you the true MOA per click value of your scope.

If your 1/4 click 15MOA/rev scope results in two groups 16.5 inches apart, your actual click value is (16.5/1.047)= 15.75/60 =.262 MOA click

Errors in tracking can be usually corrected by the scope manufacturer.

The ballistic coefficient (BC) of a bullet is a measure of its ability to overcome air resistance in flight. A higher BC, means less drag on the bullet due to air resistance, giving the bullet a flatter trajectory. Bullets with a lower BC lose velocity faster and thus tend to drop relatively quicker than higher BC bullets.

Most ammunition manufacturers list BC’s on their websites and they are readily available in look-up tables. If you are having trouble finding your BC contact the manufacturer of the ammo/bullet or give us a call.

The BC of a bullet may be given commonly  as a G1 or a G7.  This refers to the type of fixed drag curve model used to calculate the ballistics.   Generally we request the G1 coefficient value when dealing with BC’s.

The BT Ring is very easy to install:

1. Simply unscrew your top cap with a coin or the Swarovski provided tool, and remove the three dot rings. 

2. With your new Kenton BT Ring in hand, center the arrow of the new Kenton turret over the factory arrow. Press the Kenton BT Ring down till the click lines are completely covered.

3. Re-screw the top cap, and you are done!
