300 Blackout for A Kid

[Nightvisionary]

I think it'll be fine.. A sharper pulse, but about the same overall.. Good luck.. Ron

M855 has a recoil impulse of approximately 3.91 lbs. My 300 Blk hunting load with a 125 grain Sierra Pro Hunter bullet has about 6.11 lbs. While it's not heavy I certainly notice the difference.
