I talked to a gun smith this morning about rebarreling my .300 RUM SF-II, and bedding the action. I just prefer the .338 bullets, so I'm having it switched to .338 Edge. I chose the Edge over the .338 RUM, for ease of forming brass, and I have plenty of .300 RUM brass. I want the Sendero contour, and 26" length. Shilen lists a barrel as Sendero contour, so I'm leaning that way.
