Does anyone have any information on E.R. shaw rifles the mark VII? I'm thinking about buying or having another rifle built. The only custom rifle I have is in a 22-250 cal. I was wanting one in a little heavier caliber. The longest range that I have ever practiced at is about 400 yards. The folks on here shooting the looong range distances really intrigue me and got me to thinking about another rifle. I would appreciate any assistance.
