sabotloader,I use just about every thing, I think I would have to say that I use APP and APP sticks the most. I still keep and use P and RS and 50 &30gr pellets I have 4 grads of Black [I like floured blasting powder for priming the flinter] I have some Gold and some Pinnacle that I am trying I even have a couple or 3 jugs of that 777 though it just don't seem to do anything but make crud rings. The APP works well with this load either as 150 FFloose or 3 X50 gr sticks. I do have real good luck with FF and it suprises me so many people are saying its no good because of the granule size its giving me very good accuracy with high velocity and low pressure.
I will be working on it to see what the XTP's will do. Lee
