Re: Hunting caliber for girlfriend
Go with 260 or 708. That gives you a combination of readily available premium factory ammo (should you have to need some). You can use Lapua brass. Both are on the low side of efficiency in the elk department, but if your woman is this interested in picking up hunting, she would practice plenty. Bullet placement is paramount. A 50 BMG put through an elk in the wrong place will not bring down an elk, and I have been privy to elk killed with a .243. Premium handloads with 260 or 708 will cleanly take all the game you listed as important, and both rounds will lend themselves to comfortable range sessions. I chose the 260 for my girl, but she chose another man. Live and learn.
