I took out a rifle the other day to sight in a new scope. Brand new Savage, new Millet LRS-1, Millet Rings, and EGW 20MOA mount. First shot was about 20 FEET to the right of target at 100yds. OK... what the hell happened??? I mounted everything at home so I figured it would be off slightly but certainly not that much! Is there something I need to check? Mount? Rings? Any advice on scope mounting would be appreciated! Thanks!
