A question...
A question...while I understand that we each have our own pleasures with firearms, I have to wonder what you would use that round on. I mean, if you can whack a megafauna critter with a .50 BMG and it is dead, what are you going to shoot with that round? A blue whale?
And if you aren't able to destroy what you are shooting at with a .50 BMG, you'd better be calling in air support or an artillery company.
Besides, the dies and reloading press for that round have to be a few hundred dollars at the least.
Then again, I guess you could say at the local range, "That's not a Magnum cartridge, THIS is a Magnum cartridge."
Still, it would make a great coversation piece.
