Het guys, I am sort of new to this forum, not really new to muzzleloading.been reading a lot lately and I allready bought a 21" geeen mountain barrel, a knight disc extreme with the stainless barrel and I picked up a TC Grey wolf at a gun show, never been fired for 130.00. Bargains are hard to resist, so it really isn't all my fault., I have a TC Encore, Renegade, and Omega. The 21" Green mountain barrel I want to put on a Hawken style Investarms that has a 1:48 twist on it now. I think it should drop right in, What do you guys think? We live in N E wisconsin so the snow kind of makes it hard to get out and shoot, but pretty soon. Really have the ITCH now !!!!!!!!!!
