I have an extremely light weight savage in 308 (six pounds). recoil only becomes noticable to me at bullet weights abovve 165 grains. I'm not particularly recoil sensitive, but one solution would be using lighter, tougher bullets, like Barnes. I'm considering drilling 2 holes in the buttstock of my Ruger number one 416 rigby and filling them with lead shot only because the gun is muzzle heavy. But, it should also dampen recoil. Another alterntative to mercury. But, with a plastic stock, that might not be possible.
