I want to use my Northstar West trade musket for deer this year, but try as I might I never could get consistent accuracy with it. Evidently a repeatable head position is beyond me. So I fitted it with a rear sight, and now I can hold a roughly three inch group at 50 yards off the bench. Much better, and I have confidence in using it for hunting now. 75 grains of homemade powder, ticking patch, and a .600" ball get it done. Also was having too many flash in the pan without ignition, and decided the pan was too shallow. So I deepened it about twice what it was and now it's dead reliable. I guess the heat was going over the touch hole instead of into it, it's much more fun now with both mods.
