375 H&H >> 375 RUM rechamber??

From my measurements here, it appears that the 375 RUM chamber dimensions will completely clean up an existing 375 H&H chamber, with no need to set the bbl back a turn. Can anyone confirm this?

I've got my eye on a rifle here, but it is currently in 375 H&H. I'd like to get the same sort of performance as Saeed's 375-404 wildcat, and I think the 375 RUM is basically the factory equivalent of his cartridge. Easier to get dies and brass, anyway.

Is this just a simple job of running a reamer in and cleaning up the chamber, or more extensive with barrel turning, etc? I am also assuming that any standard rifling twist rate as issued for the 375 H&H will also be suitable for the 375 RUM, correct?

thanks!

I can't speak to whether the barrel will need to be turned back or not, but you almost certainly will need some work on the rails to make it feed properly, particularly if its a CRF.

Right, markb - feed changes were a given due to the much different case shape. I'm just wondering if I will have to remove the bbl and mess with all of that setup, or if I can simply run the reamer in and move on to action mods.

Pardon my ignorance but don't you have to remove the barrel for reaming?

Just run the reamer in.
If it works, give me a holler; I have a couple I want you to work on. [Big Grin]
