Default small primer in large cases

Why do manufactures put small primer pockets on large cases that typically use large primers? I picked up some 45 acp bass the other day from the range and some of them take small pistol primers, talk about a way to throw off your reloading rhythm. The cases were made by federal and they looked to be new. What's going on?

IIRC, there was a previous thread about this that surmized that .45acp was about the only caliber that Federal was loading at some plant or other that normally used the bigger primers. It would make sense to try to use the same size primers rather than make an exception for one line/caliber.

Makes since but it really sucks. I can either ream out all these cases or load with small pistol primers or throw them away. So as I said it really sucks

CCI Blazer is also using small primers in .45acp. I know because it keeps making me stop my progressive loader.

I think I read that the small primer .45 cases were those that used enviro friendly lead free primers. I found 8 of them among the batch I was priming the other night. I have not done anything with them yet but I also read that small pistol primers will work fine in place of the normal large pistol primers. I am going to research that a bit more before I load them though.

The reason 45acp was designed with large primers was because at the time pistol powder wasnt easy to ignite in a case the size of the 45acp.

Small modern pistol primers have enough heat generation to ignite pistol powder that federal uses. So its cheaper for them to streamline and use the smaller primers.

I just segragate out the small primer cases from range pickups and take those on my trips to texas and leave em where i shoot em. Or use em for trade fodder
