One of my favorite Mausers was a 6mm Rem I built on a VZ24 action; that cartridge really fits the gun well. I went with the AI version; the 6mm Rem is one that actually shows some decent gains from Improving if you're into that sort of thing. It's been quite a while but I don't recall doing any work related to making it feed well, I think it was GTG with no action modifications.
The 70gr TNT, while not a sexy high b.c. bullet, was accurate, cheap, and an absolute hammer on coyotes. It was a pretty good match for the application.
