Yes the military quickly went to a 62 grain ball ammunition requiring a faster twist than a 1:12. Who knows for sure what bullet that they intended the .22-250 to be used with it had been wild catted for several years before it was commercialized. It was very popular for pushing sub 50 grain bullets past 4000 fps.

I don't know if anyone is making a faster twist .22-250 currently. IIRC Savage or Remington maybe both made one a few years back with a 1:8 or 1:9 twist. I don't think it was that popular as without support of factory ammunition for a fast twist barrel there wasn't much of a demand for the rifles. The guys that wanted a fast twist .22-250 were just building what they wanted.
