Hey, I do follow my own advice.
Remington 700 (30-06 - 180 gr federal)
Remington 870 wingmaster (12g/3 - 00 2-1/2 buckshot and slug)
Norc M305x2 (308 and an extra rifle for spare parts, plus one's built closer to a marksman rifle, 168 SMK and SGK)
Ruger 10/22 (.22LR - 40gr dynapoints, 2000+ rounds)
Norc 1911A1 (45 ACP - 230 gr lead nose flat point, and two boxes of federal 230 gr hollowpoints)
And I'll be adding both a VZ858 and AR15 or some other 5.56 rifle to the mix soon. And I've got enough ammo for each that if I had to grab just one gun and ammo type I wouldn't be too heartbroken about leaving the rest behind. My mentality is though that home should only be abandoned if absolutely neccessay. Plus the spare weaponry can be used for bartering other goods if needed.
Now if I had to choose only one, I'd probably go with the M305 or VZ858. But why limit yourself unless it's neccessary, hmm?
