I really like all of mine, but I think my favorite is probably Ruger No.1 RSI in 7x57. I use it for everything unless there are big bears in the area. It's light (but not too light), short, extremely well balanced, fits me better than any others, is great for snap shooting or long range (250-350 yards), is just a real pleasure. I use it for sheep, deer, goat, caribou, and spike or fork moose. It wears a 1.75-6x Leupold and I really wish I'd have went with a 1.5-5x. That is really the only burr on it. I like this rifle so much that I'm customizing it now just for aesthetic reasons, not because there is anything wrong with it.
As far as the shotguns go, I have an old Stevens sxs 16 gauge that shoots as crooked as I see, so we are a perfect match in the field.
Having said all that, I wouldn't be without my 338, either. It's the "go to" rifle when the animals get big and mean in tooth and claw.
