I didn't mean 284 caliber, I meant 284 the Short action cartridge with the rebated rim. If that short action cartridge were extended out to standard action length w/ same shoulders etc then the capacity would be greater, (probably close to the same diff %wise between 7-08-284).

Then it would surpass the ai versions of standard rounds and be close to or surpassing the belted mag version. Not sure here just pulling a wild guess.
