dphobby, that's not a Gonic. It's a TC old style Contender that is probably wearing a Gonic barrel. Gonic made a few up for that rifle.

Is that a cougar on the side of the action?

You can't use Encore barrels at all but you can use many of the barrels made for the Contender.

That is a very interesting piece. I would have grabbed that one myself if I had a chance.

After I did some more research I did realize it is a contender frame with an ambidexterious thumb- hole stock. Am looking for some Gonic sabots for it cause the bore is really tight. Gonic made it tight so you would have to use their sabots and bullets. After Gonic went out of business, PR bullets took over making the sabots but at 10.00 for 50 sabots and another 10.00 for shipping, I am just putting some feelers out for some that are collecting dust in somebody's man cave.
