What about a real oddball? 356 Winchester. I have two and it's my all time favorite round. A factory Winchester model 94 Big Bore and a custom marlin with an octagonal barrel. They smack white tails and black bears with authority using 260gr gas checked cast bullets.

I have a little Ruger #3 in the back of the safe in 375 Winchester that shoots 4 inch groups. It's always been on my list to re barrel to 356Win.

Think about it, if you beat me to it you might have the only 356Win #1 ever built!
