I have a light contour 300wm m70 that's a family gun so I didn't get to choose a heavy gun but I'm turning it into more a heavy target type situation. I started by replacing the light stock with a heavy varmint/target style stock and under the barrel is air ports and a channel cut down underneath, I fitted a small lead weight towards the rear in that channel and weight is 10 pounds now, I wouldn't mind goin heavier cause why not I'm not going to carry it around the woods, so question is can I also add weight to the front of that channel? I was worried physics wise from barrel rise during recoil if its bad to have mass up front in the stock flexing? But idk if that's a valid concern
