Excellent point made by Al.
I'd consider the .300 Savage.
I once briefly owned an Arisaka that had been rechambered to .300 Savage. I can't even recall if it had been rebarreled or just rebored. I never ran a shell through it, and traded it off soon thereafter. I had spoken to a 'smith who told me .300 Savage conversions were one of the more common projects for the WWII bringbacks.
