RE: Tightening Groups with Open Sights
IMO the quality of the open sights that are on today's rifles are inferior. Alot of inaccuracy is due to poor sight quality. I personally detest the fiber optic sights. Yes they may be easy to see, but I find them to fail miserably at the range.
I suggest you put a good quality Lyman or Williams peep sight on the back, and a good qualitybead(I like white) on the front. I will bet your groups will shrink drastically, and very quickly. I also suggest you get one of the twilight rear peeps. Thy make shooting in low light conditions very easy. Also one last thing-I like 3F black powder. I believe it is more consistent. Try it. Tom.
