Henry Big Boy sights

[slickracer]

My Big Boy .357 shoots about 4 inches to the right at 25 yards. I would like to drift the front and rear sight. The rear sight is easy to adjust, however, the front site will not budge. Anyone have any ideas on drifting the front sight? I am presently using a nylon tipped punch from Dawson Precision.

Those nylon punches don't work too well on really tight sights. Clamp the barrel tightly in a padded vise and use a brass punch and a decent sized hammer. An alternative to a brass punch is an empty 22 shell on a steel punch, but solid brass is better.
The sight might have Loc-Tite on it, meaning when it does move it might be loose. If so, use some green (wicking) Loc-Tite after zeroing.
