I'll choose the zombie thread as my first post
1. Ruger LCR in 357. probably just carry 38 special though - this is for non-zombie's who want to mess with me, you won't be the only one out there and the other might not care about your life- but may want your stuff or your hideout. I'll take the lower fire rate for ease of servicing no worries about misfires.
2. Lever action rifle in same caliber. For hunting and distance protection from those other humans or if for some reason i need to shoot a zombie farther away.
3. Keltec PLR22. Main zombie destroyer. Hi-cap for if you get in a jam and small enough for smaller spaces. Also use for some smaller game hunting.
4. Becker BK7 or BK9 - Last line of defense and definitely usefully for prying, chopping, and what not.
I'd focus more on the human problem, as far as the zombies are concerned, if they're more than 30 feet away just keep walking - only shoot if you find yourself close to a group or they're blocking an escape route or something valuable.
