What the....

[GladdBag]

I think Winchester has really thrown the reloading community for a loop with their WinClean using a small pistol primer for .45 ACP. Does anybody know if Winchester is making new brass for .45 that you can buy with a small pistol primer pocket? Or is it only available on the factory WinClean ammo? This could get confusing for reloaders who are using once-fired factory ammo as well as new, unfired brass, I think. Having to use two different size primers for the same caliber. I guess the best thing to do is either pick one or the other, either buy brand-new brass with the large pistol primer pocket, or use only once-fired Winclean with the small pistol primer. I'm using Lyman's 48th edition reloading manual, and all the date supplied for .45 is using large pistol primers. How does the use of small pistol primers affect any of the ballistic or other information, if at all?

.45 ACP ammo

Years back, some of the Yugo .45 ACP ammo had small primers. It sure was unusual if you weren't expecting it. I have reloaded them with SPP, carefully of course, and they worked just fine.

I'm wondering if you'll need small pistol magnum primers for your 45 loads.

I actually used the small pistol primers for a batch of .45 with the small primer pocket, and they did work absolutely fine, better than expected, actually.

NO magnum primers are not required. The primer holes are the same size so no difference in loading. Check this other thread from a week ago about the same topic:
