  • small rifle vs small pistol primers

    So what really is the difference? I've always thought SR primers had a slightly thicker shell plate, no?

    You can use small rifle primers in pistol rounds, but not the other way around. Rifle primers have a harder cup. Some subgun guys use rifle primers in their pistol loads to prevent slam fire.

        So is there any advantage in using pistol primers? Any reason not to just stock up on small rifle primers and use them in anything requiring a small non-magnum primer?

          I've always used small rifle in my 454, that is generally recommended. I have always assumed that their construction enabled them to handle higher pressures.

          I considered large rifle in some 45WM one time based on some work a shooter had done, but found CCI LP to work best.

            I've used small rifle primers to load pistol for years. The need mainly came from shooting high pressure 38 super loads mainly to prevent primer flow. Now I use small rifle to load everything.

              So do you feel the cups are thicker/harder or something? That has always been my asumption across the board and the reason to use them for high pressures, like you say.

                    knock the retainer and material out and use your caliper and measure, it should be thicker.
