Was doing some set up for another shooter and opened a box of Lapua 223 brass. With a caliper, I found them to be a very thin 8 thou thick neck wall. Measured 3 cases at 4 locations on each case.

This is the thinnest necks I have ever measured on a 223 case and way thinner then the stuff I had a while back.

Anyone else provide some measurements?

I am not saying this is a problem....yet.

But it sure changed the bushing sizing that was going to be used. Just wondering if Lapua has now changed to this much thinner set up.

The brass was in the new blue boxes.

Let me know...

I just measured mine. They are 0.0135
I know the new 6BR brass is changed from .014 to .012
 
There is a some problems with Lapua 223 not just thickness of necks, mine measure ..0130 a few fellows shooting 223 in F/TR me included have bought over 30 boxes of lapua from Peter Dobson. I am about to send a email to Lapua and will report there response. Peter replaced 4 boxes he has tried to help.
brass I had bought from Peter 3 years ago have been fired 25 times + with no issues. there new 222 rem brass is very good.

I just measured some CF brass and it came out to .014 .008 sounds very thin but not unheard of in the BR world with tight neck chambers.
 
I routinely check the thickness of my brass with a depth micrometer to weed out thin cases and proceed with neck turning. I usually check each case at the same depth with 5-6 measurements around the neck and mark the extreme spread on the case.

About 3 months ago I measured 100 Lapua 223 Rem (1 box) obtained from P. Dobson. Extreme spread across the lot was .012" to .014". The majority of cases (70%) had neck variations of .0015". 15% were .002" and another 15% were .001".

Correct me if I'm wrong, but some Lapua brass is outsourced by them and not actually made by Lapua, just stamped so according to Sinclair Intl. .223 cases being one of them.

You are on the right track. Norma makes brass for just about all ammo and brass retailers. They will put any on head stamp that is requested.
 
Thanks for the feedback guys. 12 to 13 thou was what I had way back when so this stuff really surprised me.

Give it another measure tomorrow and will also do the outside diameter. I did measure the inside diameter and it was 222 for 2 thou neck tension.

Threw me for a loop when I measured it and did it several times cause I thought I was going nuts.

A caliper is certainly not ideal but it can work at least well enough to determine what bushing to get.

I can see from the quoted variations why neck turning continues to be used by a number of precision shooters. I would like to keep my necks as identical as possible.

Will be interesting to see what the necks box mics out at.
