Thread: 7mm RM rechambering

When I get into it I’ll fit the atlasworxs bottom metal using aics mags which will allow 3.6” COAL. That should allow a decent length projectile seating (although I don’t have any info as yet) and the actual case lengths are very similar to the RM, so should be ok there. And I found a thread of kiwi Greg that indicates the 7-375R would be suitable. And as for the cost, I assume a rechamber would be cheaper than a rebarrel, and I could utilise some projectiles and at least reuse the seating die.
