RFN...Run, don't walk.
Also buy up as much reloading components as possible, esp. primers, even if you don't reload.
Rule of thumb:
10 magazines per semi-auto rifle(20 preferable).
4-8 pistol magazines per person, per gun.
4-8 revolver speed loaders per gun, per person.
20-50,000 rounds per belt fed plus about 10 barrels and spare parts kits ( if you are lucky enough to have one).
4-5,000 rounds per person, per gun for battle rifles.
1-2,000 rounds per person, per gun for center-fire pistols;
500 rounds per person, per gun for shotguns.
10,000 rounds+ of .22 cal. LR. Have at LEAST one pistol, one revolver, one bolt action, and one lever action or semi-auto .22 cal. LR. If the shooting starts, the little .22 LR might be the most underestimated rifle on the "urban battlefield".
Misc. gear:
Have 1-5% of your ammo either on stripper clips or in the magazines at <50 percent capacity. For instance. If you have an AR 15 and 2k rounds, have 150 rounds on stripper clips, and the other 50 rounds in 5 magazines. I know thats only 10 rounds per magazine, but it saves your springs for long term storage. In an emergency, you can use the "ready mags", and given time, or a reloader while you maintain security, the rest are for stripper clips.
Next: How do you carry all of this ammo and spare parts?
Easy, have a bug out bag for all your ammo. Go to an army/navy surplus store and barter for alot of those old vietnam alice packs and frames.....stuff your ammo in here to just lug around and throw into your vehicle incase of relocation.
Always have the ability to hide your "stash". Invest in a GPS, a map, pen, paper, trash bags, shovel, pick, saw, compass, and lots of cosmoline and PVC pipe. Learn how to make a "treasure tree" to guide you to where you hide your ammo and spare parts. DO THIS NOW BECAUSE IF ANY GUN IS BANNED, THESE SUPPLIES WILL EVAPORATE! In addition, federal agents may monitor those items used to bury your "now illegal" items immediately before or after a ban through cameras, visa/mc transactions, etc.
Spare parts kits:
You should have a spare spring and pin to every gun you have. Springs and pins are pretty hard to make. You can always mill a piece of metal, but springs and pins are hard to manufacture in a pinch. Try to keep the spare parts compliant with NFA laws since some parts violate the unconstitutional 1934 NFA Act.
Thats about all I can think of on top of my head.....you guys want to comment on "when the balloon goes up" stuff to have?
I have my old SWAT bags to carry stuff in. I have two survival boxes and lots of stuff buried out on the farm.
By last inventory I have 5K+ rounds of .223, 300 rounds .300 WinMag, 1500 12 ga. 00 buck, over 1000 rounds .357 Sig but am fixing to get more, 500+ .45 ACP, 300 rounds .45 Long colt, 300 rounds .357 mag, and 1000 rounds of .22 mag ( for those time you want to be quiet ) I also love this little rifle it is a nail driver out to 80-100 yards.
I reload all but .45 ACP., .223 and .22.
When the balloon goes up?
I don’t recall where but last week I was reading about the idea of *double springing* magazines used in semi auto or full auto weapons. Yes, putting two springs in a magazine especially if the weapon tends to jam as the magazine empties. That will help guarantee that the cartridges are going to be at the top of the mag when needed.
Makes sense to me.
Drugs, like aspirin, kaopectate, antibiotics, etc.
Oh, and some Claymores. They work really well for perimeter security...
