imagine not having the mag restriction and carrying 360 rounds of 762 ammo? that has to be pretty heavy on it's own, then ad pistol mags (say 6-8?), knives, medical, handgun(s), and other misc stuff.
oh ya, this is assuming you're getting ready for a zombie party.
Not all parties have zombies and you should carry as many mags as you are physically capable of.
8 + 1 in the rifle (or 12 + 1 for an AR), 2 + 1 in the pistol, 1 CS, 3 smokes, knife, pocket tool, radio, cell, strobe, monocular, gps, maps, compass, spare batteries, light, light sticks, panel, paracord, restraints, IFAK, snivel kit, E&E, 3 litre camelbak, food, helmet, hard and soft armour and a full med pack with fluids.
After 12 hours 'pretty heavy' is an inadequate description. Worse is putting it on for the 7th straight day. Profanity is needed. Especially for an old fcuk like me.
This is why (insert deity of choice) created working out.
