It won't bother me to change out a mag box or follower.....I just don't want to be milling the action (opening feed rails) so that it becomes a permanent Ultra Mag action.
My M-70 Magnum action will pass a 26 Nos round thru the rails without a problem. But, I've read that CRF can be harder to adapt than Push Feed.
I'd suggest a discussion with your smith.
