With all the possible problems mentioned it's a good example of the importance of reloadeing VERY carefully and stay away from max loads !!

My standard .223 load is 27.5 grains of BL-C(2) and I've never come close to anything like that. I've fired that load behind 50 grain TNTs in six different guns and all with excellent results.

The soft brass theory don't really make sense either.

The main reason I like pushfeed actions for varminting rounds is exactly for this problem.....they handle this type of screwup better than any CRF action.

winchester made a bad batch of brass for a 41 mag a while back.my bud got 1,000 of them the necks would crack seating the bullets,he got ahold of them and they replaced all of them even the ones that were shot.it happens

The case and primer look like the case near the head is unsupported. But then why did the locking surface gall?.
Take care!

primer pockets looks like shoo thataway's "load developement" ..

Because I'm an anal retintive about cleaning copper out of the barrel, do you suppose there's an excess of copper fouling?

I am amazed at your acceptance of this terrible fact. It is simply one of those things that may absolutely not happen! I have never heard of such a batch coming from Norma or Lapua and I believe it would be disasterous for them if it happened. I'd rather pay a few cents extra for my brass only to be able to rely completely on it. My eyes are definitly not worth risking only for saving those cents on a second rate product.

I will say this, Dennis Sorenson, is a very competent gunsmith with a lot of experience. I would bet it ain't a gunsmithing problem.

No flies in the Norma/Lapua brass (other than price) however, there is a lot of case types that they don't make. What you gonna do for those cartridges?
Often it's not the case manfacture that messed up either, but the material supplier. When you look at the big picture of manfacturing, shops like Norma and Lapua are "small job shops" compaired to Winchester and Remington, so they can afford to be a little bit "picky" (you can afford to do that when your annual production level is less than 1 weeks worth of production at the "big boy" plants)

Dennis mentioned "feeling resistance" when you closed the bolt. What is this resistance? Is it the shoulder of the case closing fully against the chamber?
Thanks, Peter.

boulder i never said accept it i said it happens.hope where you live and everything you do or come in contact with in your life goes perfectly with no mistakes or shoddy workmanship.it was with his good fortune thet we found it when we did and they made it right at there OWN expense not ours. some people can't afford the cost of lapua or norma brass.

Boulder,
I and other BR shooters have come across bad Lupua brass. Not the norm, but it happens.

In a word, "Yes". It's a common practice for those trying to minimize headspace variances in fired cases in one particular rifle. It only works for the specific rifle you're using and would only be a matter of chance that these loads would fit the same in another rifle.

Thanks masterifleman. Now when I FL resize my cases, I have just been setting up the sizing die so that there is no play in the press ie. the bottom of the die seats firmly against the shell holder. Is it possible to just push the shoulder back a bit and not resize the whole length of the case?
Peter.

You need what the Bench Boys call a Bump die--the die body is oversized, but it will bump/set the shoulder back a couple thou at most. Usually only available for 6mmPPC and BR calibers, but you could make your own, by grinding out a standard die.

Peter
Search for PFL (Partial Full Length), and you'll find out how to set the dies to do what your wanting.
Or you could simply set your die up to fit just that rifle (the hit the shellholder methiod is "generic). Basicly that involves raising your die until it just touches the shoulder of a case that's been fired in your rifle.

Thanks tailgunner! I have a mixture of neck sizing dies and FL dies. I will try setting up the FL dies (for the rifles that I only have one of) as you suggested. In at least one rifle, my Rem 788 in 243, I have found that repeated neck sizing only has resulted in a need to Fl resize, due to the case itself expanding, rather than just the shoulder having to be set back. Don't know why.
Peter.
