Well, if I could have any one single rifle it would be a beautifully blued 24" barreled pre-'64 model 70 in 257 Roberts Ackley Improved with a lightly figured stock and my favorite 6x Swarovski scope. I also really like how the modern Ruger 77s handle. Many need a bit of trigger work but other than that, I've been pretty happy with them.
I know the poll was pretty informal but it is pretty open. Maybe another idea for a poll would be 'favorite type of rifle' where the options were, carry weight bolt rifle, heavy tactical/sniper/varmint rifle, lever action rifle, sporting semi auto rifle, military type semi auto, military surplus rifle etc...
