I shoot 25-30 rounds out of my 45/70 sometimes, and my dad owns a .450 Marlin that he likes to run alot of rounds through also. What we do when we go shooting is take a couple of towels, fold them to fit nicely on your shoulder, and throw them over your shoulder. Works really well, and they aren' t that expensive. If you want a recoil reducer just for the range, this is the way to go.
