Center-X Velocity Bingo?

Recently bought a couple bricks of Center-X from gunstore on my travels last month. Boxes were undamaged and did not appear to be tampered with in any way. I’ve bought many reloading components, powder, 22 ammo, centerfire ammo, etc from these guys without issue.

Was out yesterday rezeroing with my nrl22 rifle, was getting almost random chrono numbers, everything from 1100 down to just over 900fps. Typically I’ve been around 1054 or 1067 for my last couple lots of Center-x and they have had very respectable es/sd numbers.

This new lot is not like that at all. I put six boxes through my rifle thinking it was first a seasoning issue as I’d just cleaned my rifle, then I proceeded to check all my scope hardware (pic rail is interested into action), action screws, even rechecked barrel headspace and nut tightness. Nothing had moved or was loose.
My groups with this ammo were around 1.0-1.2” @ 50y from bench. Typically I shoot around .1-.4’s with this setup from bench and around half inch groups from props during practice.

Pulled out another box from different lot, shot ragged hole groups as I expected from this rifle. Put the suspect ammo into another solid grouping rifle from anschutz, same story, seemed like every third or fourth round had a random velocity, even had a neighbor at the next bench put it through his rim-x using a different Garmin, same results, all over the board and random speeds. Leads me to believe I might’ve gotten a bad lot or something. I’m just dumbfounded, Lapua has always been consistently consistent for me.

Guess my question is how do I proceed with this ammo that is subpar and what are my options or recourse with Lapua?
I could exchange the suspect bricks for store credit but I need the ammo for upcoming matches, both nrl22 and benchrest, so doing that wouldn’t help as match 22 is OOS everywhere.

Any advice would be much appreciated SF.
 
Please post the lot number. I haven't shot matches in a while because Center X has been out of stock online. There is not a single store in my area that has it stocked, ever.
 
Yes, please post the lot # if you would. If nothing else there may be more folks having the same issues and might be enough to get management's attention at Lapua HQ?
 
Just spoke to my lgs and they informed me they received four bricks from their supplier. They arrived not in a lapua case as usual but wrapped together with clear plastic on top of the pallet.
I bought one, another gentleman Niko from our BR club bought two and someone off the street bought number four. Niko returned his bricks for store credit weds after finding out the same thing at his tues night br practice.

Lot number posted below.

FWIW the last 3 lots of Center X I have bought have all performed very poorly compared to how it usually goes--22 ammo is a crap shoot because we are working to hit a Sharpie dot at 50 yds--If it was a squirrel then....it all does great
 
That ammo was made a few years ago, not the new packaging.
I’m not sure what year Lapua went to the current boxes.
The last Lapua I had from that era sucked also.
 
That lot # is from 2019 so you’re probably not going to get much for support from Lapua on it.
While age should not make a difference in velocities I will offer up the following info. I’ve posted in the past that may account for your issue as well as loosely packaged boxes. I had a couple of bricks of Midas+ that had accuracy issues box to box. The lot was manufactured in the same year I purchased. I pulled the bullets on one box and found that about 80% of the rounds had some of the primer component broken up and mixed in with the powder!! I can only think this may be due to some rough handling during shipping, delivery, stocking etc. It’s possible that it was a manufacturing issue but if that was the case I would think a whole lot# would be affected, not just a box here there.
 
When I practice, I want to shoot a perfect card. How can you practice with sub par ammo? If I have a flipper, flyer, or missed a condition, I want to know why. Not that the ammo can randomly do that all by itself. Brian.
Do you "know" for sure why you missed a shot, are you that "good" at reading the wind every single shot??

I'll try and figure it out. I won't shoot known trash ammo, so it won't be that. So, it was a missed condition, I was an idiot, but I highly doubt it was my ammo. Brian.

Then use the trash ammo as foulers as one of my original suggestions. RF ammo is being discussed, there is usually at least one surprise in every box of RF ammo.

Just curious, have you weighed any of the culprit ammo for discrepancies
 
As they said that ammo is from 2019. And I suspect it was improperly stored as I have some CX that got too hot (sat in 100+ weather for 5 days) that acts just like your lot. Found the lube had flowed off the bullets and the powder was clumped.

BUT, I did once get a brick of CX from a reputable dealer that had no readable lot numbers on them. Luckily it shot well.

I bought a case of CX after lot testing in OH last fall. The lot (24558/502196) I bought shot reasonably well at the test facility, but not great (the best we tested). I get a lot of vertical disparity when shooting this ammo, so I decided to have a serious look at the velocity stats using a Garmin XERO C1. Below are the cumulative results from 125 rds. fired over a period of 2 months in temperatures from 66 deg F to 80 deg F:

This case came directly from one of the Lapua distributors, so it was reasonably fresh.
 
If more shooters chronographed many boxes of ammo from the same lot they might be surprised at the results.

Not all lots of .22LR match ammo are made up of boxes that equal or nearly similar in terms of ES and SD. Boxes of ammo from the same lot can have a variety of ES and SD values. This can contribute to uneven performance on target.
 
I had the exact same issue with an older lot of Center-X and my new CZ 457 MTR. Older lot sprays all over, up to 3" at 50 yards. New lot a single ragged hole if I do my part. Out of country now and can't post the lot# at issue.
