I just sighted in my Supershadow 300wsm this week. It was accurate and the recoil was more than expected but not unmanageable. I have put about a box of Winchester 150 gr. Ballistic silvertips through it and no bruising of my shoulder. Just remember to hold onto the gun firmly and seat the gun tight against your shoulder. If not you might get hit in the forehead with your scope. Good Luck
