Well my CVA shoots powerbelts excellent with 90 grains of 2f powder. So you might want to try some 295 or 245 grain powerbelts. It also shoots Saber tooth concical in 300 grain real well. Another projectile it shoots are the 240 & 300 gr XTP made by Hornady. All of them with around 100 grains of powder and you should find something that shoots well.
