It's not that I mind atlering a cartridge but for all that you've got to go threw on this one, is the end result really worth all the trouble and expense ???? Sure the cases will last longer with the sharp shoulder, you may gain 200 or so feet per second.. seems like it's alot for a minimal gain... what will it do that the standard .280 won't, expecially in a hunting firearm.. As for brass, get some LAPUA 30/06 brass and have at it... you'll farther ahead with it than the others.. Still can't see this much for so little...
