In honor of the four weapons systems thread..

What ammo (how much of each) would you carry to support a full on bug out on foot?

I haven't carried a big pack for awhile, but I am thinking 60 pounds including all support gear (food, water, shelter), (and four weapons) is a lot of weight. I'm thinking:

10 slugs for the gauge
10 buckshot
3 20 rounders of .308
three 1911 mags
a box of .38

I'm thinking though at some point, you want to stash and return for more ammo, in case you need to hand out weapons to your buds to ambush the zombies..
