Re: Winchester Model 70 in .22-250 rebarrel to .260?
Bolt face is correct.
Will need a different mag box as the factory 22-250 mag box is shorter and set up for the larger amount of slope in body of 22-250 compared to 260. If you need one, I'm 99+% sure I have one here I could let go for a 308.
If going to a CDI bottom metal/AICS or Alpha mags then you would be good to go.
