Short version: Anyone VERY knowledgeable with PU sniper scopes? I would like to have this looked at by someone who has been there, done that.
I've gotten great groups with this rifle in the past and recently so I know the rifle itself groups well. I took it to Talladega marksmanship park this last weekend and the groups started opening up randomly and wildly after a couple hours. I noticed the main screw coming loose and bagged it up. I wasn't going to spend time at the range trying to figure out and fix the issue, I had other rifles I wanted to shoot and my shoulder was already getting tender.
The big screw at the base looks like it is meant to be able to be tightened by hand (based on the large diameter) but also has a flat head screw slot in it. I tightened it down by hand and it didn't come loose again but only shot about 10 more rounds before realizing the futility of shooting more when I don't really know if my scope is not moving.
