I know where a Kimber 8400 in 300 WSM is sitting for a good deal. I have a 300 WSM in a Win M70 EW so don't need another. I've always been intrigued by the RCM cartridges. Case head is very similar but the RCM case has a slightly smaller shoulder diameter (0.538 vs 0.515). On the surface it would seem to work. Anyone ever re-barrel a Kimber, or any other WSM based action, to the 338/300 RCM? If so, how did it feed the RCM case?
A 7-7.5 lb 33 caliber rifle would be sweet for chasing elks.
Thanks.
Why not just do the plain old 338/300 WSM since it probably works as is and you could neck up 300-325 stuff pretty easily? Not knocking your plan but the WSM brass is pretty danged easy to get ahold of.
