A Lapua oddity?

he’s and will explain later after giving the bc know it all a chance to hyperventilate

and if you can get it for center-x pricing buy all you can
 
I’ve heard about this happening (sort of) on the Eley side. When they don’t have enough that fails tenex quality control but have orders for match then have to load tenex into match boxes to meet orders. So I wonder if they couldn’t fill the brick and decided to add a X-act or seeing as they have the same lot number my thought is they ran out of boxes or one got mixed in and ran the line without being seen.

Nothing to confirm for sure but I’d be interested in hearing if it was just the one box or more ?

Basically the same ammo. All made on the same production run ( same lot number ) But just graded different some how, to make the 3 upper teirs ( why different boxes )

X act
Center X
Mias+
 
I recall seeing and explanation about getting different lot numbers with Eley whereby they fill a brick with a higher grade. It becomes test ammo as there might be one or two boxes.
I believe the explanation on Lapua lot numbers came from Glenn and I cannot find the picture quickly.
If there is any logic to the two grades having the same lot number, it may mean something to them much like CCI's lot numbers only means something to them and we cannot rely on it.

Ran out of boxes. Missed labelling. But what do you really have CenterX of X-Act?
 
You might be paying more for the same ammo. Funny I grabbed this info on a post that even Glenn commented on. So he already knows why.
Hi Justin,
You're on the right track, but I'm afraid I can't divulge the exact nature of the testing
in terms of standards that you're after. Proprietary, and strictly in-house info there.
I will say that every run of ammo, either Lapua or S-K, is accuracy tested in a series of five 10-shot groups,
as well as a 50-shot composite. The SD and ES are measured and are required to fall within a strict set of parameters,
but ultimately, it's accuracy that makes the final determination. Those that pass this initial testing
and show the best promise, are then retested. There are repeats of this same testing in several different test rifles,
in essence winnowing down the field. If it passes that testing at a certain level of accuracy,
it becomes X-Act, or is downgraded to Midas+ or Center-X, depending on where the measurements fall.
Testing of rimfires is problematic, as the ammunition tends to be so rifle specific and,
for lack of a better term, temperamental. In doing such testing at one of our Service Centers
in either Germany, Finland or Mesa, AZ, I've seen countless examples of Center-X or Midas+ outshooting X-Act,
regardless of how they tested during acceptance testing.
In those cases, count yourself fortunate that your rifle prefers the less expensive stuff.
The bottom line is, you simply can't rate match grade rimfire ammo from best to worst
strictly by the showing it makes in the test rifles. It's a start,
but you ultimately HAVE to test the lot in your particular rifle to know.
I hope this answers your, at least as far as I can answer it
without violating the specifically proprietary methods and specs.
If there's anything more we can do to be of service,
please don't hesitate to let us know. As always, we'll be glad to help.

Sincerely,

No way to tell because they both look identical
 
There's a simple explanation for this. The brick was X-Act there was one box with CX packaging. All had the same lot number.

Somehow an empty, and not yet lot number-stamped, box/package for CX found its way among the empty boxes/packages of X-Act. Once it was filled with X-Act rounds it moved along and was stamped with the same lot number as the others. It's X-Act lot number.

As you are very regimental in your shooting and document your results. It will be interesting to see if that box marked CX shows the same type of results as the nine boxes marked EXACT.
 
I shot these two boxes with the same lot number earlier this week on August 13, 2024. I also shot two boxes from each of two other lots of X-Act. I believe these three lots are all that have been available to buy this year. The results of 100 rounds at 100 yards with three lots of X-Act are shown below.

Although not conclusive by any definition, these results suggest a few things. These three lots have some very good rounds in them but the lots are very inconsistent, one especially so. The chrony results were equally unremarkable over a small sample size of two boxes of each lot. One lot had chrony results that would not be good by Center X standards.

These three lots of X-Act are not good ones. Perhaps it says something about the lots of X-Act that go to Canada.
