Yep, I hunt with a 209x50 Encore pistol and it's great. I shoot Hornady 300gr XTP/HP sabots (or T/C 300gr Shockwave sabots) over 100 grains of Pyrodex. With a scope, you should get 3-4 inch groups (or better) after some practice. I try to shoot from a 'hunting' rest, like leaning against a tree, or using a forked stick as a bipod.
I'm wondering if it's worth experimenting with Powerbelts or if I should just be satisfied with the accuracy I have now.
A couple of things: I use an earplug in my left ear, even when hunting, because these things are LOUD! You can remove the extractor because I don't see that it does anything! And buy a Peterson's Hammer Expander from Cabelas, especially if you use a scope.
Good luck!
