Encore,
Try ebay.
I've bought and sold a couple of Encore barrels there and as long as you pay attention to feedback you can usually get pretty good deals on there.
I'd say Anthony is probably right, it will probably kick like a mule, but my Encore 209X50 with 150 grains does too, and I doubt it kicks too much harder than that.

I live in Indiana as well, and I love my Encore, but I don't have any experience with shotgun barrels with it. I'd be very curious if you get one, to hear how it shoots. Anybody out there have much range experience with one?

Good Luck!
