About a month ago, I bought a used Model 70 in .300 WSM that looks to be in almost new condition. It has New Haven, Ct on the side of the barrel.
This afternoon was the first chance that I had to actually take it out and shoot it.
It has the Leupold bases and rings on it that have the adjustment screws on the rear mount. I saw that the previous owner had the rear mount slid as far to the left as it could possibly go....but didn't think much about it.
When I shot the rifle at 25 yards (just to make sure it was on paper), it printed about 2 inches high. I put about 8 clicks down and then backed up to 100 yards.
The rifle wouldn't put anything on an 18" x 18" grid target. Thinking that it was me and not being used to the trigger, I fired again. Nope, nothing. I moved the target back to 50 and nothing there either. Back to 25, and it was lined up vertically but about 7 inches horizonally to the right. I thought that was strange but put a few clicks back to the left. Nothing moved on the target face....and then I ran out of adjustment to the right on the scope. BTW, the scope is a Leupold Vari-X III 4.5-14x40.
Back in the house because I thought that something had possibly shot loose in the base screws and since I hadn't installed them, I was going to check it out.
Once I had the rings off, I immediately saw the problem. The tops of the bases were not on the same plane. Either the front is off to the left or the rear is canted off to the right side. That would explain why the rear ring was slid to the left as far as it could go. I believe that if it had Weaver type mounts/rings on it, you would not have been able to mount a scope to it they are that far out.
Ok, so now the dilemma. Is this something that Winchester will make right or did I just get the royal douching? Obviously it is a manufacturing issue from when the holes were drilled and tapped at the factory.
