I was wondering if anyone knows of a .451, 1 in 21 twist liner to put in a renegade barrel. I was thinking of a cheap Gibbs long range rifle. I also have a Great plains I could use and thought the Renegade would be better for the recoil although I never had a problem with the GPR on recoil. I want to try long distance shooting and thought it might be a way to see how I would like it before I spent the big money on a nicer rifle. I will also want a platinum nipple. I am looking for information and suggestions if you have experiences to share, or just tell me if it's crazy.
