Normally they claim the Barnes will shoot real good... I shoot a .430 diameter 300 grain XTP out of a crushed rib sabot with real good results. You can also try some shockwaves in 250 grain. All you can do is try different things. At least you got to shoot... Also if you have any Pyrodex RS, give that a try instead of Triple Se7en. It might be more fowling, but it is a very consistent powder. Good luck.
