The 408 and 375 chey tac were designed to run at normal magnum pressures of around 63k.

I know that my action is safe at 67k because KG has done the proof pressure testing for me

No seriously Greg Duley has loaded it higher to check pressures and signs and found the, so is happy that we are safe at 67k.

I really just don't get why you guys think that you have stumbled on something that other experts in the field have not been able to do to any degree.
All you have done is push the brass and action further into the danger zone, this is not something new, idiots have been doing it for years.

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 discounting that at all.
But broaden your outlook a bit and consider 'what-if' someone is doing something different that works....

What about Carlocks +P - go back 4-5 yrs or whatever - the 338 Edge has progressed has it not?

Once again you're 'presuming' the pins out of the grenade, maybe you're not shooting the same chamber, and maybe something else isnt been given away just yet.

This is all in regards to the 375, but as a broader picture the discussion of a development still has validity.

Are you wanting to go through with shear analysis?
