Thread: 300 Rum Brass Cases

Of course... but everyone talks about pressure when surely all that this is, is the cause of what we are trying to avoid... deformation. Tussocks point is valid its pressure/time = force which causes deformation which is what we are trying to avoid.

Pressure in itself is only a component of the destructive force that we are trying to avoid... it would seem not sufficient to just be talking about pressure, particularly as we cannot reliably quantify it, and we do not know the strength of every firearm/action/brass being used and we have little idea over what time that the pressure is being applied...

No deformation = no issue yes? I do acknowledge that the harder/better quality brass tends to be less progressive in showing deformation..... its good, its good, its good/its really bad ... and this is an issue..
