I am in the process of buying/rebarreling a rife for converting to a wildcat. The problem is I don't know if the typical .243 boltface will fit the .257 AI cartridge. What is the difference and if so, is the problem easy (read: reasonable) to fix? If it's a real problem the chambering will be the .260AI. Any help would be appreciated.

Boltface will be same for either.

Do you see any 'real' advantages or disadvantages to either??

Seems like they would both provide similar performance - can't see a lot of difference in the game that would be hunted with one vs. the other. Slightly heaver bullets available in 6.5mm.
