A few years ago I put together a Ruger 10-22 with an Adams & Bennett barrel and stock, and tricked out internals, trigger group and all that. Did a head-to-head test one day at the range with about 1/2 dozen different kinds of ammo including Eley Ten-X, Federal Match, and some other expensive target grade ammo. The dang thing shot Remington Thunderbolts into a significantly smaller group than anything else I tried. Go figure.
