Shot my encore today for the first time. Was a little disapppointed in the accuracy. I am shooting 120gr. of tripple se7en with a 200gr. 50cal sabot shockwave by TC.

@ 80 yards

Should I change the powder load to 150gr. could my bullet be too light? My knowledge of muzzle loading is VERY limited so any help / suggestions would be appreciated.
