Little bit of a twist of what I implied there.
You originally said your 67 was based off the LM pressures......

Hey if you've gone higher, found the pressures and come back, then sweet as - not...

As mentioned before, given the mfg receiver specs we're in a way different league to a 700, so why are limiting ourselves to those specs?
Hell when eveything was on Lee Enfield, and 1903 actions,...

Out of interest, whats the water cap of your chambering?

No - simply stating the yield of the receiver is ~165k psi as a mechanical property
I could do the shear calcs in about 10 mins with some dimensions - I have some drawings for the Barnard somewhere...

So with a receiver (Barnard for eg) with a yield of ~165k, appropriate sized lugs etc and this new chambering and brass ( take your pick or make one up) whats the stop point and what process do we go...

FL sizing was just an example of yield of the brass
If the primer pockets are opening up, then obviously its past point of yield
Not sure how it fits in to be honest LOL

FYI

Barnard P-Chey is made of 4340 hardened to 38Rockwell C
Yield strength of ~165,000 psi

Yip - the yield point/yield strength
Stress is proportional to strain and is a straight line with the gradient of the modulus of elasticity (IIRC), until it reaches yield strength in which permanent...

Huh? The elastic limit of the brass is reached on most calibers every time you fire, thus the need to full length size as the brass has yielded - there is no mention there about sizing of cases??

The whole point is you havnt even reached the elastic limit of the brass (something that happens in saw a RUM or WSM every firing)- the action is a shitload stronger to begin with

if you can fire a case 5 times without FL sizing, that you are below the yield point of the brass and operating within its elastic limit?

Wooo - hold up - noones running 88k
If barrel life is an issue when you're poking $1.50 worth of powder and $4-5 pills down the tube, with $4k of scope on top and a $6k range finder sitting beside...

Yeah.. - not the most scientific way of goign about....

And thats the whole point of this thread.. AGAIN
Its not a matter of 'feeling; whats safe, its about getting the most out of a new cartridge with no standard info
Who, what, why and when to stop?
...

Maybe I know what I'm thinkging but its not getting out, but I feel like I have repeated the same info in that post a number of times.

I;m the sort of person that will call BS on anything unless...

Steel > Brass - simple mechanics
I'd put my left nut on the fact the there hasnt been and action failure ever without brass failure - and if you are well off brass failure then you are well off...

Cos I started with 'I'll make it simple' :D

Did you read the rest though as I feel I said the same thing 10 times lol

Correct yes - but are you stating they are the same?

Sorry - should have been clearer.. 87654psi was a number I pulled out of my arse, but 88k is a number I have seen mentioned a few times as to the strength of the brass - was just wondering where that...

BINGO!
If all the ABCs are correct and the pressure gear says 200k psi then for this caliber and combo etc is 200k too high?
And if yes how and why?

As much as you think this maybe pointless, I...

Ok - I'll make it simpler.

I get a brass mfg to make me some brass I designed in .345 Superwisbanger caliber. (or .123 Humdinger)
Get the biggest gruntiest action I can get and work some loads up...

Hmmm.. not sure how to reply - obviously there are some details that are different which cant be divulged by me as its not my case design or place to do so

But are we not in a position now that...

Thanks for your valued input.
You can admit its over your head, we wont think any less of you

So a number was come about and worked to - and based on the number that was come up with, everyone else is 'overloaded'?
A number worked too with equipment that has a number of weak points.
'What...

Thats the whole point of this thread, what is the limit with something that doesnt have a standard, and what signs exhibited etc to draw to that conclusion?
A line was obviously drawn, how, what,...
