    Default Rifle vs Pistol primers

    What are the differences between rifle and pistol primers? They appear to be the same size.

    Default If I get this wrong, someone will correct. Har'ump

    Small Pistol and Small Rifle primers are the same size. Large Pistol and Large Rifle primers are NOT QUITE. The Cups are shorter in the Pistol version

    Rifle primers have tuffer (Stronger, Thicker) Cups.

    Using Pistol primers in a Rifle Cartridge could result in a pierced primer.

    Using Rifle primers in a Pistol Cartridge could result in poor ignition or none.

    I think Smitty did a great job. The key difference in my mind is the thickness (strength) of the rifle primer. For example, it is my understanding that the strength advantage is the reason that Dick Casull utilized a rifle primer in his .454 Casull pistol cartridge.

    One other thing...I never interchange pistol for rifle or rifle for pistol primers...ever.

    Rifle primers are thicker and harder than pistol primers. Smitty summed it up well!

    Default twist

    What about magnum small pistol instead of small pistol?

    I pickedup 2K small pistol mags last night at sportsmans - and plan to load all my Wife's .357 with those.......or at least the next 2000 worth. They are spose to be used for the heavier loads (W296/H110 etc) - but I will use them with some Tite Group too (which I also picked up at Sporties last night)...

    I went for primers and came home with this stuff and a Browning Xbolt too........

    Magnum primers are spose to be HOTTER than the regulars.

    Which, might be helpful.

    As to which to use, I go by the Loading Data.

    Mag. cartridges get Magnum primers.

    Ball powders get Magnum primers, (Rifle) even small cases.

    You could use only Mag. primers, OR regular, but reportedly, the choice effects your load, so you'd wanna redevelop, if you switch.
