Bl,
If you wanted to shoot Powerbelts I would go with the 300 grain Platinum's over 80 to 90 grains of 777 or even better Blackhorn 209. Powerbelts are good bullets you just can't push them to fast because they will come apart on impact. I would also look at the 195g Barnes and the 200g SST/Shockwave,,, you could push these about as fast as you like for longer shooting. If you use 777, I like to swab/clean with Mean Green window cleaner or 50/50 mix of alcohol and windshield cleaner. With BH209 all you have to do is shoot as much as you like and when you feel like cleaning use Hoppe's #9 solvent. I like CCI 209's... pellets are expensive and some what limit your load selection,,, check Wal-Mart at the end of deer season and you can pick up cans of 777 for about $11 a piece. I use the TC U-view powder measurer. Good luck with your CVA and let us know how she shoots.
