For sale today is military grade Winchester Lake City 5.56x45, these rounds were delivered to us in a large factory new 14,000 Winchester barrel and so we have separated them by weight and divided the rounds into 1,000rd portions. We weigh each 1,000rd can of ammo out to exactly 31.39 pounds, which is the weight of 1,000rds plus the ammo can. Due to the slight variation in ammo weights you may receive anywhere from 995 rounds to 1008. These projectiles contain a lead core with a FMJ copper coating and so they are not magnetic. These 55 Grain non-corrosive rounds are high quality brass that can be used to reload as well!
