I have one in 300 win mag. Grabed it at a pawn shop near my house for 250 bucks! Put a scope on it and went to the range with some factory blue box federals.. shooot a little over an inch think the average turned out to be a little over 1 1/4. Thought that is good to be getting on with. It is sitting in the rack waiting to be used.. Was thinking of turning it into a 375 Chat-taylor.. but since i got a new job i have not been home any to play with it or to get it to my gun guy to change it. I don't own a 375, but have three 30 cal rifles.. Thought it would be an easy and powerful conversion..M8x57
