You make a lot of assumptions about how strong an action is and how much pressure they can take. If you read the link posted a few pages back you will see that Kirby Allen has had lug set back in an action way before double the pressures we are talking about as you suggest. Sure a Barnard will be stronger than a Rem action but it needs to be to cope with the much higher bolt thrust generated by the Chey tac case.

You seem to suggest that as long as you are not seeing any lug setback you are safe, you may only be 500psi off this point and you would have no idea. This does not give much margin for small things to go wrong.

You have come here suggesting that KG's load is safe because no one can prove to you that it's not. Why don't you do some research and testing and prove that it is safe, a good start would be to publish the pressure figure of the load he is using. I believe that hiding it is what is leading people to suggest he is overloading.

Personally I am happy with mine at 67k and I have no problem with KG and his customers loading to whatever they think is appropriate.
I think in time the reasons to keep the load at more normal pressures could become apprent.

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 number came from thats all, though from your reference to 88k and not 87654 that you were using it as a figure.

I did a fair bit of dicking around with cases and the gun etc,
As far as pressure goes, I completely avoided the topic via strain gauge as I give it little merit regardless of brand in regards to a number. I ran racecars on dynos for years, and know the differences between machines - and its the same situation.
We're not dealing with something thats been shot for 50 yrs in the same construction of brass and receiver and thus pressure really has no influence IMO
If this case was designed before any 'magnums' were CIP or SAAMI approved, would you load to 50k psi and call it quits? of course not - thats where and how magnums were developed. Are we not talking about a magnum magnum now? if so then why are we limiting things through a set number from 30 years ago rather than working with the case to see where it goes?

If you can load the same case 5 times without FL sizing, primer pockets are tight as a tiger and there are none of the ABC signs from common sense reloading, then pressure of XXXpsi means what?
Back to a point I made earlier - overloading is loading more than a standard - the standard appears to have been set by pulling a number from thin air or from a completely different caliber 1/4 of a century old
