I want to order some primers for all the ammo I shoot (even though i don't have reloading equipment for all of them yet). I'm not 100% sure about primer sizes for the following calbers:

9mm= small pistol

40S&w= small pistol or large pistol?

.45ACP large pistol

38special small pistol??
.357 magnum small pistol or magnum pistol?

45LC/454 casull large pistol or magnum pistol??

.223 small rifle

.308 large rifle?

30-06 large rifle?
45-70?

I've seen that link, but it doesnt say specifically what calibers it just says for "most small calber" or something like that.

Falstaff,

Do you have a reloading manual?

randall had a super detailed primer chart in the past, not what you were asking, but showed this brand was .0015 larger than that brand etc. It would be really nice to compile that type of detailed info like a sticky

I do have a manual,(somewhere it's 20+ years old) I used to reload .45acp/9mm/.223 on a LEE 1,000 20 years ago. All I'm asking is what is the dividing line between small pistol and large pistol and magnum pistol. same thing with small rifle/large rifle/magnum rifle.

I reloaded thousands of rounds of .45ACp with absolutely no problems many years ago. So I don't need safety tips, or load data at this time, just wondering what the definitions of small and large caliber is.

The calibers I listed in the original post with question marks after them are the ones I'm not 100% sure on cuz I've never reloded them before.

You'll find a little mixing on the mid cal's. .45acp has been spotted with both large and small... That's close to the dividing line.

There's only 2 sizes. Large and small. When you order, look at your old brass, figure out which you've got.

After that is' Rifle or Pistol (it matters) but it's still Large and small.

Then there's to Magnum... or NOT to Magnum... that is the question. The only magnums you might need are for the .357 and maybe the .454.


If you have every single calibur listed above, you'll need to buy: Large pistol, Large pistol magnum, Small pistol, Large rifle, Small rifle. .30-06 doesn't NEED magnum, but it really won't matter much... I know very little about loading 45-70.

I currently run my .30-06 on regular large rifle, a .44 mag on regular large pistol, I don't use magnums in any of my loads and they all work just fine... i just realized, I have no small rifles lol.

Thank you very much for the polite insightful reply. Now i understand better that it's not as cut dried as i assumed, that's why i couldnt find a chart that says: 30.06 takes THIS:____ 30-30 takes THIS____ 45ACP takes THIS_____etc etc.

I'll just buy'em all!

Also, while .357 Magnum normally takes small pistol primers, I actually have about 20 cases of REM-UMC headstamped .357M brass that takes *large* pistol.

Also, you have the case of .40 S&W taking small pistol primers, but its parent cartridge, the 10mm Auto (same caliber), takes large pistol primers. This was because of the design of the guns for .40 S&W; apparently the large pistol primers were getting struck during extraction and chambering from the magazine.

Also, while .45 ACP uses (mostly) large pistol primers, .45 GAP uses small pistol.

Finally, .45 Colt takes large pistol primers...but .454 Casull takes...SMALL *RIFLE* primers! Yup, small *rifle*.

So, unfortunately, there really is no clear-cut "dividing line" at caliber. It really is cartridge-specific, and it can vary even within the same family.

The 45-70 uses large rifle as does the 30-06. The 454 uses small rifle mag but some early brass used large pistol mag. As far as mag vrs reg primers I use mag for all my reloading and never had trouble. I do have some reg primers I got cheap but usually use mag primers for everything from 204ruger to 338win mag and 45-70. I also use mag primers in 9mm to 454 casull.

FYI, http://AmmoGuide.com/ displays the appropriate primer in its Visual Comparison Tool...

http://ammoguide.com/gfx/web/joinme/vctdemo-forbct.gif

Also lists the primer diameter on the cartridge's detailed info page, in the "SPECIFICATIONS" table on the right...

http://ammoguide.com/gfx/web/saami-example.gif

When you get into older European chamberings, there are more than 2 sizes.

Go off a reloading manual (I like Sierra's a lot) and you'll be squared away. There are general rules and there are those of us that make life simple and just load small rifle in just about everything (9mm, 38 Super, 40, 223, etc.).
