I'm not a reloader so what's the difference? Is there more than two different primer loads in 45 acp?

The standard for 45 Auto has always been the large pistol primer. However, the actual charge of powder typically used is easily ignited by a small pistol primer, and the small ones are more readily available. So, some people prefer brass that uses the small primer. Brass suppliers like Starline sell 45 Auto brass with both large and small. I don't know if there is any difference in accuracy between the two but it makes a difference for the reloader since the two types of cases cannot be mixed.

As a reloader myself, I've used both and there simply is no problem with either one. The "problem" is that large primers exclusively were used for the .45 ACP for almost 100 years, so any change to small primer is automatically viewed as heretical and somehow inferior, regardless of facts.

The upside for reloaders...sometimes large pistol primers are harder to find vs small pistol primers.

Large primers are specific. Large rifle primers and large pistol primers will NOT readily interchange into any large primer pocket.

BUT…..

Small rifle and sm pistol primers are physically the same size and will interchange into a small primer pocket (rifle or pistol).

However…..
The "power/brilliance" and/or "hardness" of most any primer, will in most cases, be different.* So anyway…..THE BOOK says that one should use the "correct" specific primer for the application. LOL.

That being said, I have on OCCASION been known to use small rifle primers to prime magnum type pistol and 9mm cartridge cases (where you're suppose to use small pistol primers). Not the other way around.…like IF…..you're using a small pistol primer in a .223 REM. Because, that could/will/under some/most circumstances lead to pierced primers.

Take precautions when making ANY switch. Standard Advice : Start low and work your loads up.

Yeah……it might help with "Inventory Problems". And, I have on occasions run across great deals…..where the guy bought the "wrong" small primers for his intended application.

Aloha, Mark

PS….. *the primer manufacturer's are not very specific about certain characteristics of their primers.
