I ran into some various head stamped .45 acp brass. Federal being in the mix. After cleaning up the brass, was using a Large Pocket brush and it doesnt seem to fit in the pocket of Federal brass. So i guess the question i have is do i toss the Federal brass or is this one of those off shoot things like i need to use the small pistol primers with this brass for the .45 ACP? If i do will it produce enough of a primary charge to be effective with the .45 acp?
