Has anyone had an issue with the Axis shooting straight? From 30 yards and farther, it shoots high and right. At 50 yards at a 3 foot target I need to aim 6" below the target in order to hit the top of the target. I've tried bore sighting, laser sighting, two different scopes, the weaver base switched around, and four different brands of ammunition. The elevation turret cannot go any further down to get it to zero at 100 yards. Probably need to send back to factory. Any other ideas?
