Test Results: Barts' 6mm 105

[Bryan Litz Ballistics]

The Barts 6mm 105 has generated a good amount of interest and we've had multiple requests to test it for BC.

Here's what we got:

Barts 6mm 105 Rebated Boat Tail
G1 BC: 0.500 (average from 3000 to 1500 fps)
G7 BC: 0.257 (valid for all speeds)

This result is slightly lower than what dmoran posted in the link below, however the meplats on my lot measured slightly larger than his (0.065" vs. 0.062"). This, combined with velocity effects easily explains the ~0.5 to 2% difference in our numbers which is not much difference at all.

Thank you for the results bryan.

Bryan -

Glad to see your results !.!.!

On a note; when I computed the BC by my measurements, I did it for a velocity range from 3050 to 1500-fps, because that was near the muzzle velocities that I had for the live testing. So besides the small indifference in our meplat measurements, my computing was from a 50-fps faster starting velocity as well, which would also yield a hair stronger BC.

I just shot some at 100yd to find my powder nodes. Only shot 3 shot groups but the average was a .246 over 7 groups.

Bryan and Donavan

I appreciate both of you testing the bullets. It's nice to generate interest.

Donavan

I appreciate your work you've done with Dusty on my bullets. I'm going as quick as I can to get you some more samples to test and play with. I appreciate your expertise and all you do to help improve my product.

To everyone else:
Making the long range bullets has been an experience. I am happy that the bullet has started winning right out of gate. I'm working as hard as I can to fill orders and continue to tighten specs.

Dusty is shipping bullets just as fast as I can get them to him!

Thanks to you all for your patience and support!
