Experimenting? Psshaw, we already know they work.
Any 1911 tuned to where it won't set off even CCI primers is probably not tuned well. I shoot Winchester or Federal (any of the 4 variations), and yes even CCI primers in my 1911s because the mainspring is not super light. Use of magnum primers can be expected to increase velocity (and pressure) slightly in most loads, so a chrono check and examination for excess pressure signs after a change to magnum primers is always wise.
Right now, the Federal Large, Magnum, Match (155M) primer seems to be easier to get in these parts than any of the other LP Federals. And those work fine too.
This is Wild Bunch - no fancy guns that won't fire off primers or that you have to work over if the load changes pressure or recoil slightly.
One of the nice things about WB - no race guns!
Good luck, GJ
