magnum primers

I have 2000 magnum primers and nothing to use them in, unless I can use them in place of regular primers. I was wondering can they be used for some light 45acp loads. Thanks

    When is it appropriate to switch from standard primers to magnum primers? I can see a need when using large amounts of powder in large cases(375 h&h) but what about smaller cases (22-250)? Has any one come up with a hard and fast rule. Most reloading manuals seem a little vague.[?]

    Can I safely use magnum primers instead of standard Small Pistol in 38/357 loads without changing bullet/powder combo? Great deal on them at Wally World if I can. Plinking loads so I'm not worried about accuracy too much. Want to be able to hit what I shoot at though.[:)]

    I'd use them, just back off a bit on the powder charge. Limited test, but with my .44 mags (7.5 " barrel) I get nearly identical velocity/accuracy from 22 grains of 2400 with CCI 300 (standard) primers as I do from 21 grains with the 350 magnums.

    Go ahead and use them with your light loads. You won't notice much difference, unless you use max loads.
