Have a Model 10 and a Model 11, both in 223. The Model 10 shot very well with 69gr RMR bullet hand loads. The model 11 I shot it in a league last winter using 69gr Sierra Match King and right now I am working with the Hornady 60gr VMAX. Both will shoot 1/2moa to 300yds and the 11 will shoot 100yd clover leafs or 2 hole 3 shot groups.
