I recently loaded some new Norma brass in 7x57. A couple shots revealed very flat primers and the Mauser extractor slot dimple on the case head. Measuring case necks indicated a thickness of .020". I could have seated a bullet without resizing. They sent another box of brass- same problem. I bought some Nosler brass and plan to stick with that. I've always had good results with Norma, but now I'm not so sure. Anyone have this headache in another caliber?

So Billy, you have this brass and flattened primer problem... and you're asking mostly hopelessly stupid people to help you out???

I'd recommend using the same powder charge, but switch to Red Dot or Bullseye.

Bill, Keith is trying to injure you. You don't have a brass problem, you have a load problem. Either you have to wrong powder or the wrong weight of powder, or the wrong diameter or weight bullets. Please double check everything and your scale immediately. Verify the load in several sources. Good luck!

The load problem is caused by thick case necks. If I turn the necks to .015" the pressures are normal. Yes, Keith would injure me if he could. Keith, not all here are stupid although you are clearly in the lead. Don't let that deter you from repeating yourself.

So why did you post a reloading question when you already knew the answer Billy? I knew that even a brain dead supporter of anti-gunners like you would know better than to substitute Red Dot for a slow burning rifle powder. Do you remember when you posted this:

Another possible cause for the symptoms you described would be setting the shoulder back a bit too far during full length resizing, which can create excess head-space. But I've shared that advice here before to help pro-2nd Amendment rights guys to avoid primer flattening, case stretching, or even a complete head separation.

Carry on with your Donald Trump and NRA bashing Billy.

Actually, that neck thickness seems a bit much. The loaded round mics .324? Is that what the Nosler loads mic at the neck? If the high pressure load fired brass has enough tension to hold a bullet, it doesn't seem like there's enough room in there for normal expansion and spring back. I used to look for Norma brass, but I think for a decent while it's been nothing special. On the face of it, maybe a little neck turning would help. Oh, and stay away from heavily compressed 700x loads.

edit to add, well ain't I slow on the trigger, seems it's straightened out. Maybe, brass better suited for old military chambers, who knows. Were the original and new stuff from the same lot number.

Craig. a loaded round mikes .323. I checked an old SuperX factory load, and it mikes .314. You can see how the Norma brass is faulty. I turned necks on a few cases to .015 and got normal pressures. There definitely isn't room for normal expansion.I have 50 new cases from Nosler. Their neck thickness measures .015".

Is this the "Fraser" clone you built Bill? Post some pictures if so. I have a Rigby clone in process. Just finished the metal this weekend. Should have the stock pattern done this week. If I get lucky I might have it inlet by October.
