I shoot a 7 WSM with Berger 180 VLD's at the 1938 yard man size silhouette. I modified the throat of the reamer so I have .218 free bore that is .2843 diameter and a one and a half degree lead into the lands. 28 inch barrel and 69 grains of RL-25 produces 3150 FPS.

Never used one for hunting...yet!
