About 3/4 of the Internet is cussing because they've run into the small-primer .45s. Am I to understand you've chosen to seek them out and load them as the usual case?
I don't see anything at all wrong with small pistol primers (at least when used in the .45 ACP)
I needed some more once-fired .45 ACP brass, so it just happens that they were all small primer, but at a very good price. So, I bought the brass and the Winchester small primers ... The primers were no harder to insert than the large, and never a misfire from them.
I think they fire cleaner too than the large primers. Anyway, that's all I use now, and it won't be long until small primers is about all your going to see.
