He guys, looking for your input. I'm shooting a trued 700 SS SA chambered in 6.5CM. it has a 22" proof sendero contour in a McMillan edge Game Warden. It is topped with a VX6-HD 3-18x44 with 20MOA Talley lightweight mount/rings. The rifle shoots great. I'm shoots just about everything 1moa or better and my better loads get into the .5s. The problem I am having is a shifting POI. It shifts exactly 2MOA, and perfectly horizontal. In only happens between outings. If it shoots on way or the other it will stay that way all day or for several weeks/months. When it shifts I correct for it and it stays that way the rest of the day. I have a new mount to try that is heavier, taller and sturdier, but the perfect 2 minute horizontal shift makes me think it isn't the mount. I'm leaning towards the scope. It's happened a few times over the past year, and at first I thought it was because I was taking the stock off and changing the box mags. I haven't changed anything and it shifted again this morning. Does anybody have any thoughts or happen to have any experience with this issue?
