Is anyone have first hand experience using Federal Small Pistol Magnum (and/or Match) Primers in full house .357 loads? Federal primers have a reputation of having thinner cups than most others, but I'm not sure if its true or not, or just internet BS. I'm guessing BS.
...While I've got ya, how about hot loads using their standard primer?
I've had great results with warmer rifle loads using the Match primers, but never used any in a pistol.
It's all I shoot in .357 Magnum, the primer, not this specific load. 158 g. LSWCGC, 15.3 gr. 2400. This is the load from Hercules/Alliant for years and I have shot thoudands of them. The Fed 200 is the specified primer coincidentally. And it's softer, not thinner. Is that load "Hot" enough for you?
Federal Match 100's are all I've been using in .38 Special, .38/44 HV, and .357 for quite a while now. From target to full power stuff ( and my full power stuff is FULL POWER stuff), they work just great.
Well known the federal primers are more sensitive than others, with reduced weight hammer springs in revolvers for competition often only federal primers will fire consistently, my understanding is the primer compound is different rather than the primers being thinner or softer.
I'm not sure where your question is, beyond having used them? Yes they have thinner cups and are more sensitive, but you seem to think this might make them less capable for 357 magnum loads. There is no correlation there. Primer sensitivity and primer brisance (how "hot" they are) are two different things.
