Using the Wrong Primers...

Good post, OP....

I have 2 bricks of magnum pistol primers. Can I safely use those to fire .45 acp rounds? (I have not checked to see if they will fit the cases. Did not want to open the boxes unless I plan to use them. CCI btw.)

Safely, yes...

Reliability, well it depends on your hammer, or striker spring...
Additionally some .45 ACP brass use Small, and some use Large primers...

I can attest that large pistol primers will work in a large rifle pocket but probably not the other way around and fire just fine

Large rifle primers are 8 thousandths of an inch taller than large pistol primers. If you have enough firing pin protrusion, large pistol should work in a case designed for large rifle.

Putting large rifle in a case designed for large pistol primers will probably cause the primer to sit proud of the case base, which can cause chambering problems.

Small rifle and pistol primers share the same physical measurements, so will fit interchangeably (this is saying nothing about effects from differing chemical properties or amounts of the primer compound.)

been using small rifle for 9mm for years heck my s&b small primers say for rifle and pistol

I don't own anything that takes large rifle or large pistol primers, but 8-Thou, might be an issue...

So, are magnum pistol primers 8 thou taller than large pistol? (I suppose I could put away the lazy pills and measure them ...)

No. The difference is between large rifle and large pistol, not between standard and magnum of either flavor.

Magnum Large Pistol use in .45 ACP?

So, can I use large pistol magnum primers to load .45 ACP? (If I run out of large pistol)

[Imageview]

Shouldn't be an issue, might generate slightly more pressure (or less, or different curves) but unless you're pushing the envelope in terms of loads it shouldn't matter. 45 acp isn't a super high pressure round and should be very tolerant.

Yes

yes I do all the time in a 1911 a glock may need stock striker spring

Anyone in need of SPP or LPP and have SRP to trade, I have CCI and Winchester of both available. I prefer 41s but at this point I’ll consider regular SRP. I’m located in North LA county (Palmdale).

With 1 post, and it is about a primer-trade...
Seems pretty-shady, like get robbed in L.A. shady... for currently priceless artifacts called primers...
