A 458 Win Mag case, necked to 30 caliber, will in fact produce more back pressure on the bolt than a 30'06, but with the case straightened out to 46 caliber, that pressure will be reduced. I have no idea if it's reduced back down to 30'06 levels or not.

| I've shot thousands of rounds through a Garand, in competition and in practice. It's a wonderful action, as Patton said, the greatest battle implement ever devised. But it was never devised to handle a .458 500 grain round. I'd never shoot that. |

| Well…I’ll get to it and report back.
Shoot the largest caliber you can shoot well, and practice, practice, practice.

| Perhaps a 20,000 round endurance test will prove these theories. |
