Re: I have made a terrible mistake.
and here is the Pro-Mag, loaded, first round, racked hard as if it fired. the round sits right against the edge of the bore. its as if the bore was chamfered or rounded off, every round would go in perfectly, buuuut i aint about to do that cause that could have some dire consequences. this is the norm though, sometimes the round will catch on the collar of the round as well but this here is the most common.
