I think that Limbsavers recoil pads are much better than any other I have tried.

I have ~~ 100 hard kicking rifles.

Among the worst are 338 Win Mag 250 gr at 2645 fps from a 9.25 pound rifle including scope.
With a large grind to fit Limbsaver than I have not ground, there is no pain at all. It is like a .223, I can shoot it all day.
