After a year and a half of my shoulder replacement,recoil is big problem for me. I do own a a .243 but it is custom mauser and about 9 pounds.
I don't think one is offered in a muzzle loader which is half my elk hunting
I know a lot of people shun the muzzle brakes, but the one on my .06 cuts the recoil of a 180 gr partition to a tad above a .243.
Like anything else involved with hunting or life, you compromise to be able to continue with what you want to do.
