with primative sights you will either have to severely file down the front sight or have a lower height sight installed. My 54 Hawken printed 1' low at 50 yds and so I got the dremel tool and started shaving the front sight down which raises the bullet's point of impact down range. don't be afrid to boost the 3f charge to the 90 gr volume measurment for hunting. I tend to shoot 110 gr of 2f by volume in the 54 cal. My TC, PA flint hunter shoots 90 gr of 3f really well. I doubt if you will get consistant groups when switching patched round balls to conicals. Each may have a sweet spot but both may not impact the same area?
