Case head separation?

[fguffey]

^^^this.

another possible cause is that the die is biting into overly expanded cases. I recently reloaded some range pick ups that were really expanded, and the die would dig into the brass and cause rings like that. after getting fired, they could possibly look like that. I tossed them though.

"really expanded" and then the die dug into the brass? My shell holders have deck height of .125" and then there is the radius on the mouth of the case. I have never had a die dig into to case body that was aligned.

I purchased two dies from uninformed reloaders. They had problem sizing cases so they decided to grind the bottom of the die; they removed the radius from the bottom of the die in their effort to increase the die/presses ability to size the case.

And then there is the sizing of a case with a die that does not have case body support. Now that one just locks them up.

Use a wire? the case head separation is not something than happens suddenly and without warning. To most it seems everything handles like a doll buggy and then without warning... I would suggest the loaders get ahead of it before it happens. I also suggest the reloader get to know their rifle.

When the 308W is fired in the 30/06 the case head spaces on the shoulder of the 30/06.

Guffster, why would you presume I'm "angry"? I'm actually LMFAO at the asinine crap you falsely claim to be factual.


The above quote by you, is an incontrovertible and unequivocal impossibility.

-06 base to shoulder juncture dim...................1.948"
308 base to shoulder juncture dim..................1.559"

Difference in Base to shoulder juncture, 308 is... .389" shorter than 06. For the decimal challenged. That is 1/64' OVER 3/8"

Ergo if some numbnutz was stupid enough to to beat, pound, and ram, a much too fat 308 case, into an 06 chamber until the shoulder stopped at the front of the chamber. As the Duffster has so ignorantly and repeatedly claimed, is the case.

The case base, and primer, of the already discussed, much abused, 308 cartridge. Would be recessed into the 06 chamber by the already shown .389".

Making it ABSOFREAK'NLUTELY IMPOSSIBLE for the much abused 308 cartridge to fire. Just as member "divingin" inferred with his question.

Unless of course he is also claiming that the rifle also has a 13/32" firing pin protrusion. Which would make it dangerously unsafe to fire any 30-06 ammo.

We are lucky enough on this forum to have a casehead separations expert posting here.
He posts as either Joe Morgan or Capt Dumbsel and will be along shortly to falsely explain anything Guffey has to say.
And then there was the time my Torpedo got a 200 mph speeding ticket.

I asked you, "why are you so angry?" And then you come up with the last quote; and now you have driven most members to the curb. Again, I have suggested members think about it before placing fingers on key board. If you were level headed and could stop and think about it you should be able to answer your own question. You are lucky, we would be hard pressed to find another member on this or any other forum that understands the question.

You assumed I am wrong without considering what I have presented is irrefutable. And then there is the decency of man, he is the one that would take the time to ask where all of this information comes from. I am not the publisher, all of this stuff existed long before I got started.

The answer to your question is based on information you omitted, the information you omitted is published in all reloading manuals and is obvious in all drawings.

And I ask what 'it is' a reloader does not understand? Reloaders spend too much time intimidating others to agree. The case does not have head space, look at the drawings and again the part you do not understand is in the drawings.

I could simply and elegantly answer you question; problem, you are not capable of taking any responsibility for simply 'not knowing'. You did not earn the right to be called a reloader, you are self proclaimed. I could suggest you look at two drawings, because of your anger I do not believe you would know what you were looking at or what you were lookng for.

Here is a thread that discusses the same brass issue, and a combination of sizing and different rifles causing the brass to show the same marks.

I think I'll start cutting into cases I toss to see the insides.

The reloader should have been able to anticipate the case head separation on these cases. The best thing to ever happened to a case with a lot of tapper and a rim is P.O. Ackley and the Improved chamber.

Good visual for explaining why/how the bent paperclip test finds the weak spot.
