Bowhunter1984: CVA does not consider the Wolf to be a "magnum" rifle. They recommend a maximum charge of 100grains powder for your gun. And that's pyrodex/black powder, not the hotter triple 7. Unless you use 2 50grain triple 7 pellets, which is formulated to be the equivalent of 100grains pyrodex. The CVA technicians I've talked to were very fond of powerbelt bullets for their rifles. Cayugad's recommendations of shockwaves and Barnes is also very sound advice.
