Nothing but BH209 in mine 90grs. with 200gr. Shockwaves in blue crush rib sabots' Light recoil and very accurate.
I am so happy with my CVA Wolf that i have to say it again: trigger just as good as the Timney on my centerfire, and 1" groups with 80 grains of 777 and 250 grain SST bullets.
When i get the BH 209 that i ordered, i will try the Harvester crush rib sabots, SST and XTP bullets, and actually take pictures and post results.
This muzzleloader shot better than my 6mm Remington for quite a while. CVA makes excellent rifles. I tell you where the problem is: lots and lots of shooters who don't know how to get muzzleloaders to shoot consistently.
