I had the same problem with my CVA Accura when I got it, shots all over the place. Thru info I found on this sight I changed a few things. First I went to loose Triple 7 powder and reduced my load. Now I shoot 80g of FFg Trip 7 and a 295gr Aero Tip Power Belt and have good accuracy and plenty of power to harvest animals cleanly. I also have had good luck with Hornadays XTP bullets.
