I have a LH T3 that was re-barreled to 257 Roberts. The work was done by Jim Kobe and a Manners stock & Wyatt bottom metal was added. The barreled action was cerakoted and last year I had my local gunsmith thread the barrel and AI the chamber. It's been a safe queen for the past several years. I shot my 1st Pronghorn with it and that's about the extent of its hunting experience. It's a 1-10'' twist and I believe its a Shilen barrel. If something like this would interest you, pm me and we can discuss more about it.
