Has anyone seen this before??? I will repeat: this is new brass that was full length resized prior to being loaded one time. I thought maybe it was a "pressure sign" but one of the cases had a "silver" primer indicating one of the first 10 that I loaded with CCI-450's and 22.0 gr. of Varget. The remaining 6 were loaded with Rem. 7-1/2's and only 1 of those has slight cratering around the firing pin indentation that I noticed on my near-max load of 24.4 gr. Varget behind a Berger 25 moly.

Could it be a problem with an oversize chamber (I hope not -- this is a brand new Remington Classic with only 100 rounds thru it), or just poor quality control and a bad batch of brass???

I could understand brass that had been reloaded several times cracking in the neck area -- but brand new?? The cases were well lubed and did not drag or indicate any excessive sizing.

That'll do it every time! I had some .44 Special brass (Winchester) like that before.
Just a couple of cases out of 100. My casemaster said they were only .003" thick on that side. Unfortuantely, I didn't catch it when I loaded it. Split all the way to the rim when I fired it.

"We have completed our testing of the .17 Remington shells that you returned recently for review. The seven problem shells showed a metallurgical flaw known as a slip plane. This was caused by a colder than normal intermediate annealing step. This is a rare issue and does require firing of the shell to reveal the flaw in most instances.

We do work hard at trying to provide quality products to all our customers. The shell making processes are checked around the clock by both production personnel and a special support group working out of our Chem. Lab. We apologize for this level of performance you experienced and for the inconvenience.

To be fair, a reimbursement check for $33, to cover your shipping costs and to cover the purchase price of 100 .17 Remington shells (at Midway prices) will be sent from our accounting department within 15 business days. We appreciate you choosing Remington products and hope you will in the future."

BTW: I received the check 2 days after receipt of this letter. I thought it would have been cheaper to ship me 1-200 new cases, but who am I to complain. I still wish somebody else made brass for the 17.

I now anneal the new cases and neck turn to an even thickness before sizing and the problem ceased.

Remington new brass does appear to be very uneven over a range of calibres. New 7mm Mauser cases that I purchased were very uneven in the necks and I found that even with neck turning some cases were so thin on one side that I did not use them. 8mm brass has rather thick necks so I now neck turn 8mm mauser to an even thickness and then neck down in 2 stages to 7mm for a perfect job.

Hey jdllyons, Is there a particular reason you've not tried "necking-down" a 223Rem case made by Federal, Winchester, etc.? That way you can have any particular brand you like.

Years and years ago I had a couple of boxes of 22Hornet cases do a similar thing. I'm pretty sure they were Remington, but whoever made them replaced them 2-for-1 back then.

Remington Corelokt bullets are the best value however.

Long ago a rim split on a .22LR "Kleenbore" and a speck got in my eye. It took a trip to the eye doctor to get it out.
