BULK 300 BLACKOUT AMMO SECRETS

Well provided that, the 300 blk would be a great choice for you.  If you are likely to pistol or SBR it, you really don't shed A great deal velocity by heading shorter, which is one of several excellent things about this round.  The difference in velocity for your supers is not really lots going from a 16" to a ten" barrel, much less than five.Lo
