I was talking truck guns with a friend today. He keeps three in his truck;

243 - Marlin XS7
20 Gauge - Western Field M550CR (Mossberg 500 house brand
22 LR - Ruger 10/22

He farms in northeastern Nebraska and since he has a fair amount of free time, stereotypical Norwegian bachelor farmer that he is, he has lots of time to hunt.

I thought that those three firearms/cartridges provided good coverage for what the average guy in the lower 48 might need. What say you?
