I have recently bought a Winchester 1894 in 25-35. I am shooting 117gr Hornady round nose in it and am getting very good accuracy but it is shooting left by a few inches. I have tried to drift the front sight but it acts like it is welded in. Even using a brass punch it is starting to peen the edge of the sight base. I have a Marbles W1 tang sight on it with no windage adjustment. What can I do to get the front sight to move without boogering it up anymore. Thank you
