I shot up a bunch of GMM .223 to break in a barrel and get (I thought)
some good brass. When I measured the neck wall thickness, I found a
variation of as much as .004" and the weight was all over the place.
So, on the recommendation of my gunsmith, I bought 100 Lapua cases.
The worst case in the batch was .0005" runout. They weigh within a 1/2
grain of each other, measuring the primer pockets was a waste of time
and the flash holes are drilled instead of punched (about half of them
needed the inside of the flash hole be burred, however). Lapua says
you can fire them 10 times before they need to be annealed. I expect
they'll be part of my estate.
