357 magnum primers

kestak · September 20, 2007, 07:52 AM

Greetings,

Do I have to use small pistol magnum primers with 357 magnums or I can use normal small pistols primers?

Moreover, I did not see any load for the accurate #2 in the Accurate book but I found some loads on the web http://www.reloadammo.com/357loads.htm with accurate #2. What do you think

Thank you

Some slow burning powders will use magnum primers. Most powders do not, so standard primers will be correct.

I think it's safe to assume if the loading manual doesn't specify magnum prmers with the specific load you are using, then standard primers are called for.

Good Luck...

Joe

Exactly right-- in fact, I simply avoid loads in any caliber that call for the use of a magnum primer. Simply because I don't need yet another different component. I already have a half dozen different powders and I have primers in four sizes. To have to go get another magnum primer? Not likely to happen.

As for your question regarding AA#2 powder... I don't use that powder. And for myself personally, I wouldn't use any load I found somewhere on the internet or in a discussion forum until I could logically compare it with some real published load data from a manufacturer. And here's the best part--most of them are really good to deal with. You can call them or shoot an e-mail and see what they think of the load. Start with the powder manufacturer, and if you don't get anywhere, call up a bullet maker.

Share load data is terrific, I look high and low for it. But I'd never seat even one bullet without some corroborating evidence from a manufacturer.

Kestak, what bullet are you using ?

Greetings,

45acp from precisionbullet and the 357mags are the zero brand.
I am not looking for high accuracy or performance. Just target practicing.

Thank you

Depending on the load and what it calls for, I have used SP, SPM and SR primers in my 357 mag.

look over your loading manual carefully, it will tell you which primer you ought to be using / but if it doesn't call for a magnum primer then don't use them.

I don't use any magnum primers in .357mag or .44 mag loads.

It’s standard primers for 99% of the loads I use. It’s interesting too since I have used 2400 with both magnum and standard primers, and the standard primer loads generally give better accuracy. I’m sure the reverse could also be true, so it’s just another aspect of reloading to experiment with.

I use standard Federal primers for all my 357 loads, tried some mags but did not see any difference.

Strange, Accurate Arms used to show loads for #2 in .357 Magnum. Wonder what turned them off? It is a fast powder, subject to double charge in a big case, maybe somebody wrecked a gun.

Since my .357 'hot' loads are only made with W296, magnum primers (WSPM) are a must. All else (W231, Titegroup, etc.) use WSPs. HTH.

Me three; I use magnums with WW 296 and standards with everything else. AA #2 is kind of fast for the .357; try some AA #5 instead. Good stuff for .38s also. AA#7 and #9 are good for magnum loads, and data is plentiful. CB.

Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
