I have the RTM with the Mutant action, i've shoot many matches and it always performed without a hitch. It's more accurate than I can shoot a consistant .5'' gun. It's a switch barrel gun, I have a 260, 22-250, 7wsm amd a 338 norma mag barrels for it. All I do is change the bottom out from a short action 308 aics mag to a long action bottom and shoot the 7 and 338. The thing I really like is his back monopod that has an adjustable friction deployment, but he doesn't sell it anymore.
