You’re at camp and you’re ready for your hunt, but your ballistic turret isn’t working correctly. Why would this be? There are a few reasons, and luckily they can be worked around for your current hunt! 

Reason 1: Atmospheric Conditions

The number one reason your ballistic turret isn’t lining up with the true data would be that you are in significantly different atmospheric conditions than what your turret was cut for, and you don’t have a rangefinder to compensate. So the real answer to this problem is to grab one of our BR4’s or BLR10b’s which compensate for different atmospheric conditions, allowing you to still rely on your BDC turret, rather than switching to MOA or MILs

Reason 2: Ammo Variability

The second reason would be that you had to buy ammo off the shelf at your local gun shop, It may be the similar ammunition to what you get from us, but this is probably a different lot number, therefore your velocities will most likely be different than what your turret was cut for.

Reason 3: Rise in Velocity (Fouled Rifle)

Third example: You shot 40-60 rounds at home before the hunt. Now you have arrived and want to check zero, and maybe your rifle got bumped around on the plane, so your zero needed some adjustment. Now you’re at 80 rounds and your velocities are starting to climb, causing your impacts to go high.

So, what can you do to salvage your hunt and regain confidence in your rifle system? Here's a field hasty floating technique that will put you back in the hunt.

Range Your Target and Dial

First, range your target accurately and dial in the range on your BDC Turret. If your shots are hitting high or low, don't panic. Dial the turret up or down until you are hitting the center of the target. This step ensures that your rifle is adjusted for the correct distance.

Float Your Yardage Turret

Once you've hit center and are confident with your group, it's time to float your yardage turret. Let’s say that you shot a target that's true distance is 500 yards, but you had to dial your turret down to 450 to achieve center impacts. Simply unscrew the set screws, and float the turret to the true range of the target (in this case 500). This effectively zero's your rifle for that specific distance. You may be a little off at 100 and a little off at 1000 but the meat of your shooting distances will be right now.

You're now ready to take the shot with confidence. By zeroing at a longer distance, you create a perfect yardage mark for that specific range. This technique is especially handy in the field when you lack the time to clean and or check muzzle velocity.

In conclusion, hunting can throw unexpected challenges your way, but with the right knowledge and techniques, you can overcome them. Field hasty floating of your turret is a valuable skill that can keep your hunt on track even when atmospheric conditions and ammo variability threaten to disrupt your accuracy. So, go out there, enjoy the hunt, and trust your rifle system to get the job done!
