90's model 110 30-06, last year I slipped on rocks and landed on the rifle. The rifle between me and the rocks, hard. The fall crushed the elevation cap, that's fine it was a simmons. Bought a Nikon 4x14x40 and I can adjust the elevation all the way up and the gun is still shooting 15 inches low at 50 yards. Do I need to take the gun completely apart and torque everything back down an start over?
