My 45 colt carbine sits on Topper wood and frame. I shoot Ruger level loads exclusively in this rifle. In fact it shoots every level loads, light, medium and heavy to the red dot. I shot it at 25y, 50y, and 100y today for point of aim. dead on at 25, 2" high at 50 and 1" low at 100y with ruger loads, 2" minus groups. Opening day choice. At least 300 rounds down the tube this year so far.
