66-1 primer flow Lapua ammo

I recently bought a 66-1 from a friend (link here). I have been shooting mostly 38s out of it. I decided to buy some 158 grain 357 in bulk. I purchased 500 rounds of Lapua 158G 357 for a good price at a recent gun show. Decided to take it out and destroy some paper. Out of 20 rounds, I had 3 primer flow issues with the Lapua 357! One was so bad, I had to use a mallet to release the cylinder.

My buddy had a bunch of older 357 158 grain in his ammo storage, I shot those and no issues out of 20 I fired.

Now, that leads me to think that the primers in the 357 Lapua Ammo are too soft? Spring issue maybe?

I want to fire them in another 357 revolver to see if I have any issues. Will update. Let me know if you guys have had similar issues.

These are brand new factory rounds. That is the disconcerting part. I have bought probably 3000 rounds of various new calibers from the same guy and not a problem with any other ones.

NEW Lapua, not reloads.

About my original post. These are brand new 158 Grain Lapua rounds.

I looked at the primer strikes on the other 357 I shot that day and they were good to go, the 38s as well. The Lapua looked mushy.


I know the guy that sells them well and he will probably give me a refund. I do not want to sell them to anyone due to the soft primers.

It is a real pain when you buy 500 rounds and 3 out of 20 fail in a revolver!

Have any of you had similar issues with factory Lapua rounds in your revolver?



I will post pics when I can later.

Good point...I am going to contact them and will let you know how it goes.

UPDATE:

I contacted Lapua and they told me they do not make 357 rounds? The contact at Lapua was very responsive and is looking into it further. I sent him pics of all the rounds as shown in the attachments. Do any of you know of another Lapua manufacturer? This is very disconcerting and confusing.

More pics

More pics of brass.

Update

I got a call from Lapua. This ammo was discontinued around 10 years ago, but it is indeed ammo from the well known Lapua. I am awaiting a return email/call from customer support. they are supposed to be talking with the Finns on this to see how we can resolve it. I am not exactly happy with response so far.

I will probably end up returning it to the guy I bought it from. Sucks.

Do you have pics of the fired brass, with the messed up primers?

I was stupid and threw them in my brass bucket. Need to dig them out. Will post pic when I do.
