Incepient case head seperation after 3 loads.

[fguffey]

May I enter your exclusive club of people that can pour a cast of a slightly tapered round hole and measure it accurately?

jerseyjoe, if you want to enter the club you have too much ambition. Anyhow, the other shooter/reloaders lives on the Easter Shores of new Jersey. I found him on another forum asking about chamber casting, the other forum is one of those socially dysfunctional forums. No one warned him about what he was getting into when they started the insults, I apologized on the behalf of the forum and then had him contact me by email and phone. It did not take him long; my opinion, the forum could have benefited from his knowledge and skills. There are a few of those members on that forum that are members on this forum; they are easy to pick out.

There is no doubt you are a very knowledgeable loader, Mr. Guffey.

I lurked this forum for quite a while before I joined.

I don't have anywhere near the experience reloading compared to most on this sight.

I do have 42 years of experience as a machinist and tool & die maker, and will try to help with any problems relating to such matters.

Coincidentally, I grew up on the shore in Bricktown, NJ.

Hence, my user name.

So if indeed the brass was manufactured wrong wouldnt there quality control catch the problem.

It could be that your chamber is a bit on the big side and your brass is on the small side. Matt

They should have, but as I mentioned in an earlier post about the 45acp Winchester brass I found the same problem with, things fall through the cracks.

I think we found a verdict hers some pics of that batch of NEW brass on a machinist angle finder set at 90 degrees. Also ill include some pics of strang marks on the brass. Ther rim varys by .005" thickness around the rim. Tell me if you think these are crooked. All cases are rotated 90 degrees so 4 veiws.

Did the same test on my 243 brass. Hornady and rem look great (not crooked) and my old brass doesnt have any ridges. All of my fired winchester brass has ridges and about 3/4 of the new are noticeably crooked against the square. Also the heads are not beveled even and the extractor groove looks uneven. Not impressed with winchester brass right now. Even looked at my new lapua brass in 22-250 it is perfectly even in body and head. All of the. Buldges are excatly 180 degrees away from a mark in the extractor groove. It looks like a tool mark from when they draw the cases. It doesnt line up with the headstamp perfect but seeems to be where the long side of the crooked brass is where the bulge shows up.

You may have your problem diagnosed. When I suggested checking squareness of the cases I was thinking fired cases and overlooking the obvious...that the new cases may be at fault and not the rifle. KISS

 

[fguffey]

I have 'V' blocks, run-out gages, small turn tables and I have been known to lay a case down on its side and roll them when looking for a wobble. I also have a gage that no one else uses, it is not complicated but it could take 4 hours to explain.

I do not have 'new' Winchester cases. All of the cases I have chambered and fired mirrored the chamber the case was fired in. I have purchases thousands of cases from firing ranges; before purchasing I sorted, my favorite cases are/were cases that have been fired in trashy old long chambers. That would be a chamber that is long from the shoulder of the chamber to the bolt face. When sizing a case I use the case to off set the length of the chamber, for me it is easier to start with a case that will not allow the bolt to close.

I have one rifle with a chamber that is .002" longer than a field reject length gage; it is not easy to find fired cases that have been fired in a chamber that is that long. For me? Not a problem: I use 280 Remington cases for that chamber.

Is this a new press that you are using?

[Mtstalker]

It is a new press but ive loaded 5 diffrent rifles with it and only have the 270 brass doing this. My 243 brass was all done on my old press

An oxymoron.

That's about how long it would take us to explain a Stoney point to you. I have a Stoney point, a caliper, a set of mics and a Stoney point bullet comparator and that's all I need to measure a fired or sized case and seating depth. It's not rocket science. Matt

No, it's exposives science. After all we are just making little bombs and detonating them in a controled environment. dedogs

FWIW we don't play with explosives. Propellants, and they're being ignited, not detonated. So a store can sell smokeless powder over the counter to any Tom, Dick, or Harry, no ID required. (But you know that, "dedogs", hence the emoticons. )

I have looked this post over fairly well what I see is a terrible chamber job if I was going to keep this rifle I would screw a gun barrel on fit up an chambered by a reputable gunsmith.
