I think that's the thing about this cartridge though. Is it better than a 30BR? Maybe not, but has anyone (other than maybe Mike) put enough time and effort into testing a Major vs a 30BR to truly know which one outperforms which? I doubt it.
The benefit to a Major is being able to use a PPC boltface, and not give anything up to a 30BR, while not having to mess around with brass. Rebate rims, open bolt face etc. Similar velocity, bullet selection, powder selection, and less recoil.
But that's really all this is, just another option. If it's not your cup of tea, don't drink it?
