My favorite rifle is either of my Swedish Mausers. One is a rifle, one is a carbine. I have better/newer/other rifles, and I want to love them more, but the simplicity and accuracy of those Mausers, combined with their soft-shooting characteristics make them awfully hard to beat.
My second favorite rifle is quickly becoming my Marlin 39. My 10/22 is probably a touch more accurate (although I am splitting hairs there), but as my buddy says, the 39 is man-sized. I really enjoy shooting that rifle!
My favorite to shoot is my K31. If I had to choose between my Mausers and it, the Mausers would win every time, but that straight-pull action is perversely fun to shoot.
