Swarovski BT Ballistic Turret Instructions
Firearms, ammunition and rifle scopes have become
more advanced over the last few years allowing for the
harvesting of game at longer distances than previously
thought possible. The Ballistic Turret (BT) series of
rifle scopes from SWAROVSKI OPTIK is one such
The ballistic turret gives the hunter the means to set
a zero distance plus 3 more easy to set, see and use
down range distance settings of your choosing – 4
clearly marked settings. Once set up, you simply turn
the turret a few clicks up to the appropriate downrange
distance desired so you can hold the crosshair
precisely where you want the bullet to hit. To get back
to your zero setting, simply turn the turret back where it
will automatically stop at your pre-set zero setting.
The shooter will still have to accurately determine
distance to the target (as with a laser range finder),
account for wind when necessary, and keep in mind
the limitations of the cartridge being used with the
game being hunted.
The following information shows you short step-by-step
instructions to set up your own ballistic turret.
At www.SwarovskiOptik.com/bt you will find the BT Ballistic Calculator and detailed instructions on how to
Easy, accurate and practical:
- You can mount and accurately adjust your ballistic turret to your firearm in just a few steps.
- In addition to the 4 marked distances, there are additional distance settings available.
- A specifically-developed ballistics program calculates for you the values that you need (number of clicks) for your desired distances.
- After the BT is set up the turret will return to the zero setting when turned back down. The colored down range settings make the down range adjustments
easy, even in low light conditions.
Unscrew the cap of the ballistic turret using the key
supplied or an adequate coin.
Use the graduated dial by pulling upwards.
Step 3: You will now have the 5 removable parts in front of you.
All other parts are affixed to the rifle scope.
Assembly and positioning
Step 1: Sight in the elevation by turning the top section of the dial as shown in figure 01. If you are sighting in at 100 yards, turn to the right or left until your elevation is dead on at 100 yards. This will become the zero setting during further assembly. To do this, turn the upper detent ring in the required direction. Use the keyring opener if necessary.
Step 2: After sighting in to your desired zero setting, turn the
lower section of the dial in a clockwise direction until it stops as shown in figure 02.
Step 3: Attach the coupling (c) on top of the dials so that the arrow on the coupling lines up with the white dot at the base of the turret. You have now made the setting for your desired zero range. If procedure 02 was followed, the coupling will always stop at this zero setting when the turret is turned clockwise.
Step 4: Please check whether the entire control range (just under 360°) is accessible. To this end, turn the coupling in a counterclockwise direction all the way to the end stop. Now turn the coupling back again to the end stop.
Step 5: For your second down range distance, turn the coupling
in a counterclockwise direction by the necessary
number of clicks and attach the (green) marking ring (B1) so that the green dot is directly above the
white dot on the base of the turret. The necessary
number of clicks can be determined by the BT Ballistic
Calculator on our web site, by sighting in at the desired
down range distance or by calling customer service at 570-220-3159.
Step 6: Your third (yellow marking ring) and fourth (red marking
ring) down range distances can be determined in the
same way as you made them in section five. (See Sight In Example at the end of the tutorial.)
Step 7: Now turn the entire turret in a clockwise direction all the way to the end stop at the zero setting.
Step 8: Attach the cap (A) such that the directional tab lines up with the arrow and with the dot on the rifle scope. The cap can be screwed on with the key that was supplied.
Your ballistic turret is now ready for use.
Function and practical tips
Once the ballistic turret is fully assembled at your predetermined distances, the entire turret must be turned to the appropriate setting. In the .30-06 example on
the next page, if you have a 300 yard shot, turn the
turret to the yellow setting, hold the crosshair where
you want the bullet to hit and shoot.
Should you desire to set a further distance than your furthest (red) down range distance you can by using the
ballistic turret’s white scale. The number of clicks
needed for this purpose can be determined by the BT Ballistic Calculator
on our website or by calling customer service at 800-426-3089.
The Ballistic Calculator will show this farthest
distance as total clicks from the 1st or zero setting.
Write your personal distances on one of the decals supplied. You can place it wherever you wish – and you
will surely hit your target faster.
Sight In Example
In this following example you are sighting in a .30-06 using a 180 gr bullet with a ballistic coefficient of 0.480 at a velocity of 2700 fps. You want to make the settings to be zeroed at 100 yards with the other down-range settings to be at 200, 300 and 400 yards. Zero your rifle at 100 yards as described in steps 01 through 03 for your 1st setting. The 2nd setting at 200 yards requires you come up 8 clicks to set the green marking ring.
The 3rd (yellow-300 yds) setting requires you come up 11 more clicks from the green 200 yard setting to hit dead on at 300 yards. The 4th (red-400 yds) setting requires that you come up 13 more clicks from the
yellow 300 setting to hit dead on at 400 yards. Another way to visualize this is that you have come up a total of 32 clicks (8+11+13=32) to get to the 400 yard or red setting.
