Thread: Wilcats and Pressure

That's exactly it Kimjon.
And especially so for new cases as opposed to others that are necked up/down eyc

OK seeing as my last post was to long winded.... let me have another go...

The suggestion is that good brass because it is stronger does not show the signs of pressure in a strong action.

If the failure of brass is the problem that we are trying to avoid, then what does it matter what the pressure is as long as there are no pressure signs?

If the action isn't strong enough, we should be seeing pressure signs in the brass before failure?

So 50K or 70K or even 90K is irrelevent if there is no pressure signs in the brass?

There is not a lot between no signs and failure on some of the hard brass. Personally I would like a large safety margin back from the point of failure to protect my eyes, face, life if anything is to ever go wrong. If you are at the limit all it takes is a slight overcharge or high temp to cause failure. It seems a lot of people forget what is at stake if it all goes wrong.

So what was the 'limit' in your gun?

It was not taken to the "limit" as it would risk my action, brass and the person shooting it.

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, and why was it drawn there and not further up?

OK so what the limit.... in your gun

Do you not follow the tried and accepted practice of loading up incrementally until the first signs of pressure and then backing off a subjective safe amount?

Because we are using actions and brass similar to say 338 lapua which has a safe working pressure of around 65-67k. What makes you think that it's sweet to run cheytac brass up to 88k when nothing else has a safe working pressure that high? Have you confirmed with Barnard that they believe their action is fine to take that much bolt thrust?
