I cannot justify two .308 rifles for the same purpose.
Well I always figure that's what my FAMILY is for. And I mean extended family. What if my uncle or aunt or my wife's cousin or my son-in-law's cousin showed up? What would THEY shoot? You could say it's all about being a polite and considerate host.
And what about when I pass? Are some of my kids and grand kids and great grand kids going to get NO guns just because the old guy didn't buy enough when he could? Well that's just sad.
(I figure when I have to work hard to justify a purchase I'll just enjoy it that much more.)
