Too late. At least for LR and the .223. I still shoot it at mid range (600 yards and less with 80-class and lighter bullets) where some of my best scores have come with a .223 bolt gun. But for LR and the Palma class, I found it was much easier to handle the recoil of the 308 (including the 200gr Hybrids) than to get (and keep) the 90s shooting well. There's still a huge upside for 90s and the .223, of course, but that's more work and greater likelihood of the gun/load deciding not to shoot at a big match. I got burned by the 90s shooting well at home (including 1000 yards), then not holding elevation at all when I got to Nationals one year.
