Ed,

Your Wolf is a 1-28" twist, which means that it probably won't shoot round balls accurately. You can always try- use a light powder charge (50 or 60 grains or so 777) and try at 50 yards to see if you can get it to shoot straight. The Wolf shoots sabots very accurately, and can shoot conicals, but is not designed for round balls.

Another option- it is usually possible to install a scope on traditional rifles. I've seen several people with scopes installed on sidelocks. Have you ever thought about putting a scope on your Frontier? That would be one option for you.

If you want to stick with the Wolf, you'd probably be better off using a sabotted round (if it's legal where you live). Several people on this site have Wolf's and they seem to shoot well with a wide variety of rounds. A good starting point is the 240 grain XTP and 80 grains of 777- that would be an excellent deer load out to at least 100 yards- plenty for your purposes.
