WRE1;
I am in full agreement, in fact in a follow up post I stated I would not expose either me or a gun to such abuse. Just thought I'd stir the pot a bit.
The Mag 20 loads with 1 1/4 oz shot from that 6 1/4 lb gun had Stout, though not abusive, recoil. This load had a good bit lower velocity than a "High Brass (3 3/4 DE-1 1/4 oz) 12 gauge load.
As stated it was quite usable for its intended purpose in hunting situations where only a few shots would be fired. Its accumulative affects would become abusive if a large unmber of shots were fired in a short period of time.
