Gregory, originally that 99 could have been in 303 Savage, 30-30, 300 Savage, or 308 depending on model and year. After rebarreling, might have been a "270 Savage" if he wanted it to work with minimal change to the rotors/etc. That's basically a 300 Savage cartridge necked down to .277. With a good gunsmith, could have been made into other 270 cartridges also.
