shifting point of aim with non adjustable sights

[Dphariss]

So, I have been shooting a musket that has the front sight and rear sight soldered to the barrel. The rear sight is slide adjustable for elevation, but not for windage.
Currently it is shooting about 6" right at 100 yds. How would I go about shifting that group to the left.
The front sight is a little thicker than I like, so I thought about removing a bit of metal from one side or the other, and maybe that would help. Which side would I file so send the bullets left?
I thought about maybe also widening the rear sight, but it is already a pretty wide notch.
Any ideas or suggestions?

Hi Justin
Send me the sight radius and I can send you the amount to move the sight to move the impact 6” at 100. With a sight radius is 30”, for example,  you need to move .050” +- or move each .025”

Or simply go back to post # 4 and do it yourself

 The best front sight on a trade gun I built was off just a hair to the left. It was actually a solder on underlug for a round barrel. But when I got out and really practiced shooting the gun I found I didn’t need to move the sight at all. My trade gun has a 30 inch barrel, and I did have to bend it slightly to get the elevation right. But I found that if I used the apex where the sight and base intersected as a peep sight she was dead on. This little trade gun shot like a rifle out to about a hundred yards or a little farther.
