I have a .204 Savage that I have shot around 1500-2000 rounds out of. The glass is a Leoupold VS3L 20. Lately my targets look terrible-4" at 200 yd! The gun use to hold an easy 1/2" group at 200. I have never bumped the scope or gun and I shoot the same hand loads as I always have. 27.1 grs rl15 40 vmax rem71/2. I have checked the screws on the scope mounting several time and re- torqued the stock. Nothing jumps out at me.
