Just a few years ago I saw a video regarding the test center of someone who works there and he said that's how they determine which packaging is used for a particular lot. It's base on their test results for each lot.
I have both C-X and SKLR in a couple different lots. They look identical right down to the ID markings on the case head. I subjected a batch of each to rim thickness and weight sorting and they sorted out much differently. The rim thickness of C-X had less variance and the weight did as well. I don't remember the exact rim numbers but where the SKLR had as much a 1 grain weight variation the C-X was within .1 all weighted on my FX120 scale.
Wow great results! Those are amazing. I'd definitely have taken that CX lot you got! Who chambered your Krieger barrel?From 3weeks ago

As you can see, the difference between CX and M+ here is minor but tangible, especially at 100m.
I was able to get almost a case of CX (they were 3 bricks short) so was able to also purchase half case of M+ to use at long range or against my archrival when he shows up.
What I thought was so interesting is how poorly some lots shot. For example:

Obviously rejected...
To me, this shows how important lot testing is.
Glad you asked that cuz I was wondering too. Surely those who have tested there know what it means.
And apparently those numbers are metric.?
Just to point out that there are 6 values given that relate to DHH(ie. mean,std dev, min, max, etc). Clearly the straight DHH between the 9th and 10th shots in the group is about as meaningless measurement of precision that possibly exists.What more can one ask for!
That is my understanding but I've never been there myself. Both of you guys have nice 20 shot groups.
Nice find, thanks for posting that info.Eley actually published the difference between 10x, match, and team. They used rsd radial standard deviation. Its in their latest catalog.
The two times I’ve gone in person what Luke would do is pick the best few 10 shot group lots and do twenty shot groups with the best lots for a final test. I’m a poor so don’t sneer at my CZ’s results. On this trip we had to shoot it in the stock without the rear action lug screwed in, long story. I’m shipping a different CZ out to Mesa today.
For those interested, I saw a post that at this time Lapua is limiting purchases to a case per quarter, ie. every 3 months. I don't have that first hand but worth checking if you are considering going.
From what I read on the website it seems Mesa is the best option right now. The Ohio location appears to be booked out solid for around the next 4-5 months.
It’s the only option as the person who does the testing left and they are looking for a replacement. I got a notice that my appointment in Ohio had been cancelled and would be rescheduled when they found a replacement. I’m still in the queue though.
