Only problem would be figuring out which magazine works best with the .250, and then finding some. I would bet that either the .244/.257R or the .243/.308 might work, but the best match would be the .300 Savage mags. Not easy to find any more!
FYi, there ARE many used 760s out there, but by FAR the greatest number are .30-06s or .270s. The shorter cartridge versions (.222, .223, .243, .244, .257, .300, .308, .35, and .358) are much less common. Probably the most common of the short ctg. versions is the .308 (several Federal agencies once used first the .30-06 and then the .308 versions for service rifles back in the 1950s and early 1960s). Some local and state police also used them, mostly in the same two calibers. I suspect they liked them because they were also using 870s or some other pump riot gun.
