Primer question.
what is the difference between small rifle primers and small pistol primers is it unsafe to use small pistol primers in a .223 or is that a big no no. the reason I ask is because local shop doesnt have any small rifle primers in stock only small pistol primers . I compared a spent small rifle primer to that of the pistol primers and they are the same size however I'd rather not take a chance if it is unsafe to do so.

Pistols operate at a max pressure of about 35,000 PSI, a rifle can go up to 60,000 Plus. The primers are designed to account for that pressure difference. It is VERY dangerous to shoot a pistol primer in a small rifle cartridge.
Always use the correct primer for the correct application.0 -
Thanks I'll have to gripe to get them to get the right primers in Idiot behind counter said they were the same thing. 0 -
Another thing, there are MIL-Spec primers for uses in guns that do not a firing pin return spring. Those primers are designed to use in Military type cartridges, especially the 7.62X39.
If you have a choice ask for CCI. I have also found WOLF primers to be very consistent.0 -
Its been said you can swap small rifle for small pistol if your pistol can dent em. But never swap small pistol for use in a rifle, it will perferate them, bad ju ju. cup pressure is to high. 0 -
Do not use pistol primers in rifle loads except certain ones like 22 Hornet.
Prior to the great primer shortage, I used only CCI primers. During that time, I used other brands for pistol but never changed brands for rifle cartridges.
CCI#41 is the mil-spec small rifle primer designed for semiauto military type rifles. I don't know if they're really required(many reloaders don't use them) but I use them in all the AR ammo I load. They produce slightly larger groups than the standard CCI#400. I saw a new primer offering which I intend to try-Federal AR Match. Supposedly designed for the AR with improved accuracy potential over the CCI#41.0
