I used a 300 grain platinum powerbelt with triple 7 pellets (100 grain ) and dropped my 5x5 Roosevelt bull in at 120 yards one shot with my cva accura
Those platinums are better than the regular Powerbelts but I’ll take Barnes or Bloodlines any day of the week.
I've got an CVA Accura V2. I've been loading Pyrodex 50/50 for a couple years with several different bullets. I have yet to gain any real accuracy with that powder. The gun does best if I swab the barrel every round (pain in the butt and not practical while hunting.) I'd try with Triple 7 powder or Whitehot to start with, and stay away from the Pyrodex altogether.
I found that Hornady SST bullets seemed to outperform Powerbelt Aerolites. I shot my deer in the neck this year with a Powerbelt and it didn't kill him. He just dropped and flailed on the ground till I climbed down from my blind and walked out and put a second round in him. The bullet fragmented in his neck, which is apparently a frequent problem with this load.
I tried the Barnes TMZs pre-season this year. I couldn't get them down the muzzle with less than half my body weight leaning on the rod. They are super hard to seat. I'd stay away from these duds.
Once you've put some shots downrange with your new gun, you might want to consider changing out the sights. I was unhappy with the large front fiber optic sight and I like a rear ghost ring for open sights. With the original setup, I couldn't accurately hold on the target when the front sight was larger than the target at 100 yards. If shooting at a distance requiring hold-over with those fiber optic sights, you loose sight of the target completely. Here's a couple articles on changing sight out for a more effective setup (IMHO). I used a Pedersoli globe sight (instead of the Lyman), which comes with a better set of inserts. The gohunt article has a good Q&A section at the bottom addressing problems in getting it set up.
