As well as in shorter barrel lengths (~8″) the 300BLK is far top-quality for supersonics, at the least. Extensive barrel 300BLK is around pointless IMO, you can find other rounds that outperform it handily in exactly the same platform, with exact same length barrels. Felt recoil will vary from shooter https://winstonr371jtc5.blogozz.com/profile
