My ASSUMPTION has been that if the factory marked the barrel as a 250-3000 that it has a 1 in 14 twist. Likewise, if it is marked 250 SAV it has a 1 in 10 twist. Furthermore, to add to David's comment, I can't imagine Savage making 1 in 14 barrels as late as 1975 when the CD was introduced. My 1976 CD is marked 250 SAV.

My rifle did not come with a sling, so can't help there.
