I believe the 300 Savage case is to short to form a 250-3000 case by about .042" and the 250-3000 case neck is to small to upsize to .308 dia. Don't think I want to stretch a .257 out to 30 cal. Brass is still available for both rds. at Graf and Sons.
You can make either one for 308 brass but the Savage lever action may be kinda particular on the chambering,bolt gun not so much. It's just simpler to buy the brass.
