I purchased a CVA Accura V2 after reading mostly great reviews. However after 5 months of different loose powder and sabot/bullet combinations I have not found any combination to shoot consistent. I have tried Pyrodex, triple 7 and Blackhorn (yes I bought the breech plug). I have tried hornady XTP's, Barnes MZ's and TMZ's, shockwaves, PR bullets in an array of weights, and scorpion PT's. I have not tried power belts because if these are the only bullets that this gun will shoot consistantly than I don't want it. I have tried every powder/bullet combo in 10gr increments from 80 to 120gr. I have used Fiocchi, Federal, Winchester 209's with the Blackhorn and triple 7 and Remington clean bore primers with the other powders. I have tried swabbing every shot to shooting without swabbing. I have waited over 10min between shots to allow barrel to completely cool. I have put 3 different scopes on this gun along with the current 800$ zeiss to rule that out. My best 100yd group thus far is a 3" group at best with PR 300gr dead centers and 105gr of triple 7. The next day the same combo shot over 8". I know this is long winded but I am looking for any possible ideas besides the gun being faulty and wanted to explain what I've tried in the 200 plus unsuccessful rounds I have fired through this thing. I'm at the end of my patience. Any ideas are greatly appreciated.
