1. I loaded some super sonic 300 Black Out the other day and went to the range. Long story short, I picked up to of the rounds and I could pull the bullets right out. I normally check for this when I load my ammo so here is the question: Did the recoil of my gun cause these bullets to come loose from the case? If so, do you taper crimp ammo in your AR15's?

2. I have a .308, 20" barrel, 1-10 twist. What is your favorite SUB-Sonic load for this combo??

Thanks.

Sounds like the case was improperly sized. The neck tension should at the very least retain the bullet in the brass. For most semi-auto applications I will add some degree of taper crimp or if the projectile has a cannelure I would "factory" crimp. I do not recommend crimping if you are really trying for small or 1/2 moa groups.
