What's going on? First shot out of my cold hunting rifle is PERFECT. Inch and a half high at 100 yards. The next shots, 2-3-4-5 are high right and about a 3-4 inch group. I can let the rifle sit, pick it up cold the next day and PERFECT shot, next shots are high right. I've changed nothing from last year. Same powder, same box of bullets, primer, brass ect. I even double checked OGIVE. I've heard of "one shot rifles"...but it was perfect last year. I'm not on the edge of twist rate...bullet weight...but I am shooting Reduced Loads for Wife. 1-10 twist .308, 165 gr RL15 41gr at 2500 FPS, .02 off lands. I would think "SCOPE" if it wasnt dead on when cold the next day. Any Thoughts ?
