About 2 months ago I bought a 93r17. Its accurate enough to hunt squirrels with. For Christmas my girlfriend bought me a stock from Boyd's. the varmint. I headed out to the range and found it to be extremely accurate at 25 yards so I moved out to 50 yards and found that it was hitting about 2 and a half inches high. Before it would be almost dead on. I'm trying to figure out why that is. I torqued it to 15 inch pounds and then went up to 20 because Boyd's recommends the stock torqued between 14 and 26 inch pounds. The difference happens when I was at either torques. Any information at all will be greatly appreciated thank you.
