I'm not aware of its use in modern cartridge rifles, with the exception of the 6.5 x 52 Carcano, which I just learned about recently.It is also harder to rifle the barrel, some custom modern center fire barrels have it in today
I saw where a barrel transitions from a 1:12 to a 1:8 for a .223 (5.56).
I know from experience (watching a couple friends try to over spin a 6.5 ppc.) too much spin will cause the projectile to disintegrate. To much centrifugal (or angular momentum, as one of our members would say) force on the bullet.
