Hello everyone, my name is Greg. I just recently got into long range shooting and I need help diagnosing something. I have been shooting tight groups with my rifle which is a 700 SPS action mated to a HS Precision stock. I have put 57 rounds through thus far and have yet to have a group measure over an inch and have shot on average 1/4 MOA so far, but I have one problem. After I shoot a good group of three, my groups seem to move around the target. I will fire a series of shots and I will have a tight group, and then either on the same day or next time I go out, the group will move. Today I shot slightly right about an inch to the right from where I was shooting last time I was out, so I adjust my scope and get back to center, and then maybe a group or two later, it will be off again, but again, wherever it moved, it groups tight. I did this today and walked all over the place and then adjusted it before it got to dark to shoot. I was back on center, and the last group measured 1/4 inch. This is frustrating. I wonder if it is just me screwing up but I also worried that my scope is doing weird things? I have a Super Sniper 10 x 42 mounted on a TPS rail and using Super Sniper rings. I checked all my screws and everything is tight. I just don't see how I can shoot tight groups and all of a sudden be off an inch or two in some whacky direction, and then adjust my scope back to center and shoot good again, and then all of a sudden be screwed up again. I am using a bipod up front and a Caldwell bag holding the rear. I also checked the action screws and they are still torqued to 65 inch pounds. Maybe I should mount the gun on a good rest or sled to see if it is just me? I know this sounds crazy but any ideas? Thanks!
Greg
