Assuming it to be true that only certain bullets can be used, I guarantee it isn't a 50 grain. They don't even make a 50 grain for the 06. It would have to be at least a 150 grain.
Actually, the 30-06 accelerator bulletsare 50 grains. Of course, they are illegal now, as are the 30-30 accelerators, which are 50 grains.
