ZV headstamped 5.56 Brass Problems

Trying to get a batch of .223 loaded.I have mixed headstamped military brass,mostly Lake City.When I started seating bullets most of the brass marked ZV necks were too loose to hold the bullet.The bullet would go to the crimp ring and the case mouth was too loose at the crimp ring and the bullet would move up and down.I tried to adjust the seating die to crimp it,but it had to be adjusted so far in it would push the shoulder of the brass back.The LC and other brass are working fine.Bad Brass or am I doing something wrong?

Measure the thickness of the necks and buy an expander ball that is .004 less than the bullet diameter plus the neck thickness times two.
You night try a Lee Factory Crimp die, collet squeezing as opposed to an edge.
The brass you have may be thinner in the neck. It may also be too soft to hold the bullet when seated-if this is the problem, there's no remedy.
But, for something as dirt common as .223, I'd just scrap it.
