A lot of compromises the OP will find. I put a break on my .06. I can still shoot my 6.5 Swede. No problem with my .243. I can get off about 4 shots with my 50 cal muzzle loader. Worst is my 20 gauge Franchi semi auto.That seems to bother my shoulder more than anything.
My old 38-55 with the curved steel butt plate still gets a few rounds run thru it,but they are cast and mild loads
Most of my plinking is with a handgun now. 38 sp loads in .357mag cases or 22's
