I got 1.5 inch groups with 245gr areotips out of my CVA Wolfwith 100gr Pyrodex pellets 2 weeks ago at 50 yards, ( I know not too impressive yet) at least I plan on tuning a little more. This weekend I plan to try loose Pyrodex RS and move out to 100yds. I didn't shoot that far out last time because I had my father in law with who has been ill and the range was muddy.But if I can get the same results at 100 yds by tweeking things a little I'll be satisfied to use those Power Beltsthis fall deer hunting.
