I have a Model 24 .22 LR/20 ga. 3" Mag. It was my first gun back in the early 70's. It's a bit heavy for backpacking but is about the most versatile gun going. I recently shot slugs through it and it was reasonably accurate (4" @ 50 yards or so.)

Yesterday I bought a friends spare .303 British for 75 bucks. That and a box of ammo will be stashed out in the RV which serves as my "long-term" (2 weeks) remote survival cache.
