Small Pistol Primer ? - The Firearms Forum

Ron01013 · 02-22-2012, 05:33 AM

I'm loading 357s with Remington 51/2
9s - 40s - 38s with Rem 11/2

Can I use 51/2 on all loads?
All loads are middle of load range with Bullseye Pistol powder
Thanks again,
Ron

YES, as a matter of fact, Remington has a warning label on the box of 1 1/2 primers stating NOT to use them in high pressure rounds like the 40 S&W.

Quote:

In pistol cartridges, the 1-1/2 small pistol primer should not be used in the 357 Magnum, 357 SIG or the 40 S&W. The 5-1/2 small pistol primer is the proper selection for these rounds

Steve, What about the 38s & 9s?
Is the 51/2 too strong for them?
tks,
Ron

the 5.5s will work great in both.

The reason the 1.5s exist is for the low pressure revolver and auto cartridges normally associated with aging autos and wheelguns of yesteryear. the cup is thinner and makes it easy for a weak hammer spring to detonate the cartidge. And since its used in conjuction with low pressure rounds there isnt much concern for a ruptured primer. But the 1.5s can easily blow in high pressure pistol rounds like the .40 and the 9mm.

Hi Ron. I see this question pop up a lot - concerning the use of magnum (particularly small pistol ) interchangeably in standard loads and vice-versa.

The load data in reloading manuals are labratory tested. Having said that, I'd say NOT to use any substitutes in your components - powder/primers - unless you are willing to take the risk to yourself or your firearm. If your manual(s) state 1 1/2- use that. If they call for 5 1/2, go with that.

I am sure that there are many folks who interchange data and have had no problems, but why take the risk? So you go out and buy a brick of standard pistol primers and a brick of magnum pistol primers. Just keep them seperate and pay attention to your loading manual and loading process.
