All time favorite due to looks right now is my M91/56 Mosin-Nagant. Fairly light, packs a whallop for deer up to elk, maybe moose at close range if I feel dumb enough
My favorite long gun of all time due to practicality, however, would have to be the Mossberg 500. not tweaked out to look tacticool but a standard 500A with 5 round magazine (gives you the maximum 5 loads in the 3" shells) and a cantilevered rifled barrel with smoothbore on the side. Simplicity and necessity as art.
(wood stock/pump all the way too)
ETA: As far as dream rifle though, I would have to say probably a bolt rifle in .308 win/7.62 NATO (for practicality) in a McMillian stock. Awe heck just say M40 and that would probably be it. Top it with a 3-9x50 Leupold (I could take a Burris too) with a sunshade and we are set for coyote, deer, maybe elk at 100-150 yds, do matches. I think I know what my next project is going to be
(once I get done with my Benelli, AR-15, 59/66 SKS, Springfield M1903, AK-47... I think it's going to be a while and a lot of dough though
)
