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.

Steve, I'l get some photos of my "Fraser" to you soon. Could you post them here?

yeah sure I can post them for you.

I am wrapping up the clean up on a .303 Fraser as well.

Hopefully you can also post some pics of the Fraser action and metal work outside of its stock.

LRF, My " Fraser" rifle is one I built after I'd been outbid on a real one. I think they're one of the most elegant bolt rifles of all time, and if I can't own one, I decided to make my own version. It lacks engraving, that unique bolt handle, and some other nice details. I hope though that it does capture some of the Fraser touch.

I just measured neck diameter on a loaded round using the Nosler brass. It mikes .314"- same as vintage WW ammo. Those of you loading new Norma brass beware. Check the necks before you shoot. PS: In my rifle the N orma load chambers without resistance, but the tolerances are too close for normal pressures.

Bill, when I made my post I should have been more clear and directed it to SKB, as I think he was talking about the bolt gun Fraser he acquired a short time ago. Sorry.
I did know you had built a Fraser but I don't remember if you had previously posted pics. I would like to see them if possible.
I also built a Fraser and you are absolutely correct and I agree, they are the most elegant of the European SS rifles. IMHO I have previously posted pics here but its been a long time ago. Mine is in 405 Win and is all engraved in english scrolls by Roger Sampson.

I have had two Fraser m98 take down rifles in recently. The one currently in is one a slant box Oberndorf standard length action in .303 British. I am doing a very mild clean up on it. It is almost done. I will post pics when it is complete.

After all those prosperous Hope and Change years your anti-gun hero Barack Hussein Obama brought you, I would think you should have been able to win an auction for a Fraser rifle Billy.

Keith, My President didn't lie about the weather. Keep reading the National Enquirer. I think it's making you smarter.

He probably did Bill. I know you're aware of it, but don't care to admit it, because of your preference for a divided country to advance your agenda, eh?

You know barak's been spending all his irrelevant time accumulating personal wealth, when he could be an honest enviro warrior for free, right? Anyone who is buying a lavish private beach front mansion isn't too worried about rising sea levels. He would thank you for your service to pc, but that's beneath him. Do you deplorables get summer beach houses, or feel good crumbs designed to keep the misery level high enough to obscure a little thinking?

Billy, your president... your anti-gun Liberal Left Democrat hero Barack Hussein Obama... spent eight years lying to us about the climate. He told us that the ocean level was rising and the sea would inundate coastal communities around the planet. He told us that that massive storms and hurricanes resulting from global warming would batter our shores like no time in history.

So tell us then Billy, if Obama seriously believed that, then why is he endangering himself and his family by buying a $15 million mansion on the coast at Martha's Vineyard?

And why does a guy who spent his entire life bashing the rich feel that he needs a $15 million mansion on the coast at Martha's Vineyard anyway? Wouldn't it provide better optics if he lived modestly and did volunteer work helping the millions who became homeless Welfare cases under his reign?

Keith, Your science background and your status as a climate change denier mark you as ineducable. What possible concern of yours is it what house Obama buys? Do you think he might have consulted you first? Do you feel he's ruining your neighborhood? If you think he didn't do enough to rescue the economy from Bush, you're even dumber than you sound. Dumber than Craig.

Billy, where did I ever once deny that we have climate change? We have had climate change for as long as the earth has had an atmosphere. Climate change is driven by the sun, the ocean, and by volcanic activity, far more than the miniscule influence by man.

My science background is exactly what leads me to believe that the climate hysteria driven by Liberal Left anti-gun Democrats is based upon deception, and the manipulation of weak minds... such as yours Billy. You won't read this, but I'll post some links for those who aren't so agenda driven and foolish as to vote for anti-gunners:

If we go by prehistoric CO2 levels, at our current CO2 level, the ocean sea levels should be over 100 feet higher than they are right now. But they aren't, are they? And humans didn't even exist at that time either, so who do we blame for that? If dinosaurs had only driven Prius's, they might still be here.

And if you can make it all the way to the end of this article (don't even try Billy, this is way over your head), it will be seen that the correlation between CO2 levels and temperatures over the last 400,000 years being used to support the Global Warming propaganda from the Liberal Left is cherry-picking data at its' finest:

But Liberals and the Fake News have largely been successful in suppressing the 2009 Climate-gate scandal. They just stopped talking about Global Warming until the controversy died down, but they knew they could come right back and continue the B.S.

When he was selling snake oil in chicago, barry was given a shady campaign donation, in the form of a zoning loophole, so that he could have the biggest lot in his neighborhood. Fast foreward to two years ago and he picks up an eight plus million shack in dc. Now, the summer spread on the beach. Hey, doesn't that old fool, bern have a beach house.

I'm offended that you rank based on dumbness, it's not fair to you. On the dumbness scale, barry's decisions could only go unquestioned by the.....well does the scale go into the negatives?

No, we really don't care what barry parlays off the taxpayer in the misery industry, but it's a teaching moment in hypocrisy, right? He's tell'in us climate this-n-that, you're parroting what he's tell'in, ah, no big deal. I guess we aren't all equal and fighting for the climate, just the dumb ones.

Makes one wonder. Do you think the baraks amigos, that're hammering law abiding US citizens in a war against the second, are just as hypocritical, yet counting on the very same dumb ones to be useful idiots? Hmmm, what say you mr. science?

I say you still can't write a sentence that would pass remedial English. Your head is so full of Fox propaganda that everything you say comes across like scrambled eggs. Do you feel comfortable with the notion that your fool in the WH deserves the real estate he has title to? He's no more fit to be in public office than Keith is.

I think my brain is more of the pickled egg variety, but I use it to thank goodness I wasn't lucky enough to be in your remedial english class. Otherwise, I doubt the third time would've been the charm.

Yes, I'm comfortable. Just think, if your President wouldn't have donated his entire paycheck to worthy causes, we'd think a charitable donation was watching beeto get a hair cut or change a tire, eh? Wouldn't have been possible unless he deserves everything he owns, right? What were you thinking, vote for lizbeth and tax him to pieces unless he self impeaches? So, you think keith is cabinet appointment material, hmmm.
