I don't know what is a good scope.
I just read some reviews of that gun on Midwayusa and people had good luck with Powerbelts and sabot-type bullets. Either one should be fine.
I personally don't subscribe to using the pellet-form of powder because you cannot vary the amount of powder other than choosing between 2 pellets or 3 pellets. But if that's what you like, then just try it and see how it shoots. Others were getting 2-inch groups at 100-yards, and a few got a little better than that (with various different powders).
That's just my $0.02. Happy shootin' !!
