I have a Genesis also. It shoots Hornady FPB 300 gr over 100 gr loose Pyrodex really well. I've shot a few deer with it from say 30 yds to just over 100, and this combination performs very well.
My plan is to try BH209 when the Pyrodex runs out. I don't know if the plug it has will work with BH209, does anyone else know? Thanks.
