I've picked up some .45 ACP range brass here and there which seems to use small pistol primers. How common is this? Which brass manufacturers use small pistol primers in .45 ACP? So far, the culprits are: S&B Speer GFL Am I smoking carpet fibers? Am I missing something here? I guess I'll load them up with small pistol primers, the next time I am getting ready to switch the Dillon over to do a 9mm run.
