That's a beautiful rifle, and an outstanding cartridge. Congrats!!!
One of the partners at my lawfirm has one of the Weatherby MOA's in .257 Wby Mag. But...I'm not a partner, and don't make the partner dinero... So, if I was getting a .257 caliber rifle, I'd have to stick with a .25-06 in order to be able to afford the ammo. I couldn't afford to shoot at a cost of over $50 per box...
