Ack! I can't help myself (although I'm stretching to connect the Subject line to the question):
A terrible question to ask - it's causing me severe mental stress... I don't have any I want to give up. I guess the answer for me would be my old Ruger M77 30-06. It's a real beater for looks now, but it's a death ray in my hands - we have a lot of experiences with each other...
Any good, accurate bolt action in 308, preferably with Herr Mauser's big extractor, might be smarter, but that's my pick and I'm sticking to it...
