Looking for a Contender carbine barrel in 7mm. Either 7-30 Waters or 7mm TCU. Not interested in any chambering more "wildcat" than those two.
A factory 21-inch tapered carbine barrel is ideal. Doesn't need the rear sight.
An aftermarket 7-30 barrel from a quality maker, 19-23 inches, with some degree of taper on it would also be good. Don't want the weight or balance of a 23-inch full bull.
In 7mm TCU, something approximating a Super 16 would be great, but I prefer the longer barrels for velocity, especially if it's 7-30 Waters.
