I have been trying to develop a reasonable 200 yd. load in my .54 cal. Dimick plains rifle with a 1-60" twist. A 24" group is where I am currently at. Even though for the last 2 yrs I have won our gong match, its nothing to brag about. Shooting 90 gr. OE 1 1/2 powder, have tried .530, .535 balls and various duck patching. Fired patches look good. So I am wiling to try a felt wad under ball next. If you have had some success with this combo, what thickness of felt, and is it lubed? Sure would like to get at least a 12" group. I have a globe front and adjustable plains style rear sight and have no problem seeing the target while on the bench.
thanks
