Ross M-10 rear sight question/problem

[rayg]

The Ross M-10 rifle I just recently aquired has two stamps on it that have a crown over crossed flags and DPC. between the poles. Not sure what that stamp is, maybe indicating "Drill Purpose condemmed" which could indicate obsolete. I'm not sure. Most DP stamped rifles I've seen had just a large DP stamped on them.
Any way I checked it out and everything appeared to be ok. It has an excellent bore. I also made sure the bolt had been put together right. Took it to the range and put 20 rds through it without a problem. The cases looked ok so the chamber has not been enlarged. Shot good groups but 6" to the left at 50 yrds.
The problem is the windage sight is set too far to the right. I'm assuming the little serarated gears in the front of the leaf need to be rotated/turned to move the windage zero over but the gears will not turn or move more the a quarter turn. Am I doing something wrong? Ray
