.45 acp primer

[colt1911fan]

.45 acp reqires a large pistol primer is that assumption correct?

 

[rikman]

Yes, but some cheap factory ammo sold at wallyword,Federal , has small primers.

Im just now getting into reloading pistol ammo so does the 357 mag require large pistol magnum primers?

 

[rikman]

No, 357 is a small pistol magnum primer. Just always refer to what the loading manual. Interesting info is also in the manuals, ESP Hornady's ,Speer. Primers are also of different brisance, fancy word for intensity, some are hotter than others. The Lyman manual and speer has good info on this.

Enjoy this great hobby

Yes, as stated, 45 acp is large pistol primers, accept the mentioned anomaly's. Also be weary of 45 gap, they have small pistol primers also and look very similar to 45 acp.

No, the 357 mag takes small pistol primers.

Just a suggestion, do yourself a favor and pick up at least a couple of reloading manuals. Every manual states which cartridge uses which primer size.

I'd start with the lyman 49th.

So far my experience has been that Speer is small primer. Some Federal is small primer and some is large. And I think I have seen some Blazer Brass that is small primer.

When I started loading for .45 ACP I ordered a bunch of brass from someone and assumed (my mistake) they were large primer.

I then ordered 2000 large primers.

Imagine my annoyance when the brass showed up and it was Speer with small primers.

Luckily a friend of mine had been collecting large primer brass and I had 250 or so small primers so I could get started loading.

That is not correct. The 45ACP that contains the small pistol primer is of the Non-toxix variety and is far from the cheaped. It is marked under names such as Super Clean NT.

I wish they would make all of it with SP's from here forward.

Traditionally, the 45 ACP used a Large Pistol Primer. In receint years in the attempt to go "Green", some ammo is/was produced with lead free primers. The lead free primers loaded in the 45 ACP are small pistol size. http://www.the-range.biz/Nontoxic_Load_Development_7Apr06.pdf

Not all small pistol primed .45 acp brass is from Non-Toxic ammunition. You're going to be seeing more of it in the future, so you might just as well get used to it. There are numerous threads on this subject on all the reloading forums, with all kinds of theories, most of which are incorrect.

It doesn't take a large primer to ignite the small amount of powder in the .45 acp case, but "we've always done it that way". I won't rehash the reasons for going to the small pistol primer, but if one were to do a search, they would find the many threads on the subject.

Hope this helps.

Forget the dog or the wife (just don't tell her this) but the RELOADING MANUALS are our best friends.

They will tell you whether you want magnum primers or not.
As mentioned above 45ACP brass mfgs have made small & large primered brass. :banghead:
And 357mag uses small pistol primers.

SOME 357mag recipes will call for small pistol magnum primers, some will call for standard small pistol primers.
