Lake City .223 brass??

[STS]

Anyone have any info on the quality of the 2009 LC brass? I have read it has the highest case capacity on all .223 brass. How about case wall thickness uniformity? Anyone have a neck thickness measurement?

FWIW I have a bunch of 08' and it's great stuff. Haven't worried about capacity as I load for accuracy and velocities are acceptable.
I can easily get 23.9 of Varget in'm and could probably get over 25 and still have plenty of room in the neck.
Case walls on the 08's are good, neck walls running in the 11 an 12's. I'm lucky enough to have a factory gun with a good chamber and runnout isn't an issue. I've turned a few just to see if I gained anything with accuracy but there was little noted change, again it's afactory gun.
The issue for me wasn't so much what year class the stuff was, it's about having the same year class.
All of mine are 2 dot 08 nato stamp. (the same run)

Arent the primers crimped on the later lake city brass? Just curious. I use all I can get from the 80's and early90's that I have left . Little to no crimp.

New LC brass has no crimp, just purchased 500 new LC 09 223 never fired

I just bought 500 pieces of "LC 09" brass from Midway, what actually showed up at my door was LC 10, but big deal.
I've been pretty impressed by the quality of this brass so far. It arrived in good shape, I saw some people complaining about oxidation and dents which wasn't present on mine, all the measurements I took were very consistent, length, neck width, etc. varying less than 0.001. I haven't really weight sorted it because I generally don't bother with that, but the ones I did weigh fell in the 92.2gr range with only two outliers. Neck thickness ranged from 0.013 at the thickest outlier to 0.010 at the thinnest outlier with the majority having a thickness average of 0.0115 and often varying less than 0.001.
I have a general rule of thumb that if the neck thickness varies between 5-10% of my selected thickness, then I turn it just to knock off the high side. For example I want to run a neck thickness of 0.011, then if the brass varies 0.0005-0.0011 I'll probably turn it. Obviously over 10% is unquestionably turned, and under 5% I don't bother. For these I turned them to 0.0115 and all necks were no less than 75% cleaned up.
The primer pockets were in pristine condition with sharp corners and identical depths so I didn't bother taking a uniformer to them, and the flash holes were also very nice such that 50% had no burr, and the other 50% had a burr so slight it took a flick of the wrist to knock it out.
I'm loving this brass so far, and while Lapua may be slightly higher quality and uniformity of neck thickness (I was really hoping to be able to run a no turn neck) I'll gladly put in the elbow grease to fix the miniscule differences, particularly when considering the money I saved over Lapua brass.

I just got a batch of Lake City 09 and the flash holes were off-center on every one of them. Better have a look!!!!
