I've got one in a Model 70 XTR that I found with a very sad barrel. It now wears a 26" 3 groove Stainless Pac-Nor with a 1~9" twist. As expected it has the Winchester slanted box magazine to feed the semi-rimmed cartridges, and it feeds them absolutely perfectly.
I have no problem getting 4000 fps out of 40 grain Ballistic Tips, about 3600 from a 55 grain bullet and 3100 fps from a 69 grain Sierra. Not quite a 22-250, but much more fun.
Wouldn't change it for anything.
