45acp primer pockets?

I hear that some brass now use small pistol primers. Would a large pistol primer still go in the pocket? I have alot of mixed brass the pockets look the same, but some have smaller flash hole.

98% of what you see in .45 ACP is large primer. If you DO find a few small primer ones, just toss or scrap them. Unless you have enough to make it a dedicated set for loading, it isn't worth the effort.
Please enlighten me. At one time did the .45 use a small primer. I load WWII .45's. These are the standard large primer. Since the .45 has been with us quite a while and having not seen a casing from before WWII, I was just thinking it would be neat to have a couple with the small primer just to show off. Thanks
Current Winchester and Federal NT marked brass is the small primer brass that is seen now.
They exist, but are in the definite minority.

There is some small primer .45 ammo coming through now without the NT mark. Did they just not bother with the headstamp or are they also lead free and not marked? I don't know but don't think it matters to the reloader. If you have a lot of them, they will load, if you don't, they are not worth fooling with.
Similarly, the only quantity production of non-corrosive WWII primers was for .30 M1 carbine - because there was no major use of Small Rifle primers by the US military prior to the adoption of the carbine cartridge in the early '40s (just some experimental stuff like .276 Pederson).
Editsorry about my lack of writing skills. I did not mean to imply that I agree with 2 different primer sizes on the same cartridge. . I really want to say we are as reloaders lucky the ammo makers don't make cases that would not be reloadable or at best much harder for us to reload. on the same note IMHO ammo control would be much easier then gun control. My shtf supply is powder primers and cases + bullets both already made and lead +molds for hundreds of thousands of bullets. . Yes I know that I could never survive long enough to run out but I could supply 200 good pistol shooter for a long time.
I have a bunch of current small primer 45ACP segregated to be loaded, fired and resegregated.

Why would Winchester and Fereral increase the PITA factor for the guys like me that think finding a once fire casing in the grass at the range like finding money on the ground? It also increases, as has already been stated, the "danger" factor of reloading. Just makes me wonder if they are really on our side.
The NT priming compound is "hotter" than the old.
In order to keep the pressure pulse in the safe range, with a Lg primer, there wasn't enough compound thickness to insure reliable ignition. By going to the smaller cup, they could get enough thickness to insure reliable ignition.
JMHO, but if you're so brain dead that you can't tell the difference in priming force (when trying to force a large primer into a small hole), than you shouldn't own a firearm, let alone reload ammo.
BTW, they also made large and small primer 357mag cases.
And 38 Special before that. And several other revolver cartridges as well.
BTW, the Frankford Arsenal #27 primer in the early Cal .45 cartridges was to avoid confusion with the larger Cal .30 rifle primer.
They were .204 dia. and only made for about two years during the war. (WW-II) Rare to find one these days.
Mike Whiskey is correct.("At one time did the .45 use a small primer. I load WWII .45's.".........during ww2 SOME .45's were loaded with a smaller primer (larger than a small pistol primer, smaller than a large one).

Frankford Arsenal actually started using the #27 primer in 1911. It was by design, not just something that happened for no reason. Not all commercial manufacturers that were contracted with to make government ammunition used the small primer. Frankford continued to use it for many years but I don't have exact dates of when it was discontinued or phased out. The #27 primer was still being manufactured as late as the KW.
