TC made a small run of the 14" barrels in 30-30 AI. I also am one of those ppl who are looking for one of these barrels as it's one of the few that I don't have. If anyone has one that they'd like too part with........pls feel free too contact me at email@example.com.
A little update. Midway 30-30AI T/C Contender barrel was on back order. On searching the web I found a lot of information on some good custom barrels that were about the same price as the T/C barrel. Match Grade Machine Custom Thompson Center Encore, Contender, and G2 barrels - MGM (MGM) They have a bunch of calibers made up on the 30-30 case. I ordered a Shilen SS 14" 30-30AI shipped for $285.00 . They have about a 6 week delivery. I should get my barrel in about a week and a half.
I was very temped to order their 6.5-30-30 but the cost of a set of dies turned me off. I got a set of Lee 30-30AI dies. I have never had any trouble out of the Lee dies myself.
