300 rounds is considered a lite basic load, 600 rounds is considered about enough for one long patrol, this in 5.56 along with 50 to 100 rounds of pistol.
300 rounds can go bye, bye in less than hour of hard use, 600 rounds in less than a day?
10 days, 3000 to 6000 rounds per person.
In an emergency, 10 days of hard use per month, times 6 months, 18,000 to 36,000 rounds over this span, means, how much ammo you got on hand???
Factor in no resupply, and everyone looking to pick up more ammo in any emergency,,,
Having 3000 to 6000 rounds in a REAL hard use period is not so much ammo to have on hand folks.
If you are willing to bet your life, that any emergency will last one hour of hard use, have 300 rounds.
Or 3000 rounds, 1 hour per day for 10 days of hard use.
or 25,000 rounds for a few months, fine.
25,000 rounds is about right for a real emergncy that might last six months, after that, we use ROCKS???
In any emergency where the use of a firearm is needed for more than ten days, buy ammo now, most of these new rifles being bought will run empty in less than one hour.
A spare rifle or two is not bad either, a new Colt M-16 will be burned up in less than an hour of hard use, been there and done that.
You may find me dead in a ditch one day, but I will be up to my waist in spent rifle brass.
