What's more Accurate in 22" BBL

[Iron Worker]

Savage Predator and Remington Predator what caliber will be more accurate 22-250 0r 243

the 243's case design is inherently more efficient / accurate, but I doubt you'd notice the difference in a factory rifle. both cartridges are a little on the overbore side for each cal, but my money would be on the 243.
