Find some Big Game powder.
Put 47.5 grains in a case with a Winchester Large Rifle Magnum primer.
Seat a 140 Partition at 2.805"
Report back.

Thats what I would love to see on my targets for sure. But I am 100% sure that if I set a Partition at 2.805" I might not even get the bolt closed on my gun.
I've heard good things about Big Game in this cartridge. Enough so that I would definitely think about experimenting one day. For now I'm gonna have to stick with H414 as it shows too much promise.
