I am in the process of designing my own 50bmg and am having trouble finding a buttpad that will fit. With my receiver tube being 2.25" diameter outside, that means my buttplate is 2.25" wide. The widest buttpad I have found is the Limbsaver large grind-to-fit at 2.06 wide. So I guess what I am curious about is, does anyone know of a blank piece of rubber (6"x6" or so) that I can cut my own buttpad out of? Ideally, something 1"-1.50" thick and I would like something fairly soft to absorb some of the 50's recoil. Any help would be appreciated!
