Pawn shop find, it has a low front sight that appears to be soldered on and shot about a foot hi at 15 yd. The breach is a snail but not hoked and barrel is pined. There is about 6" of rifled barrel. Is there another option to dove tailing a higher front sight. The sights (triangle front and V rear) would probably be closer if I could see well enough to take a very fine bead. I tried 20 gr of FFF goex, 440 ball and pillow ticking patch and will try 25 and 15 grains next time out. Am not looking forward to cutting a dove tail but think I can handle it if necessary.
