My dads Marlin 336 he bought in 1950. It was sighted in when he bought it and the scope has never been touched since. The gun has been dropped down the side of a mountain in West Texas and had everything other kind of abuse done to it but whenever you pick it up it still shoots where you aim it. My new favorite is my new .450 Marlin I bought for hog hunting. Everybody kidded me at first when I bought it but now everybody grabs it when they head out at night to go hog hunting.
