PA24,

Please do not yell.

I do understand the original question and what the thread has evolved into. I want to know what a proof is before I agree or disagree. My last post should have provided insight into my thoughts on this.

If one wants to shoot modern ammo that may be 11,500 PSI they should consider if the gun will handle any overpressure. Otherwise stick with low pressure loads.

I am certainly not opposed to lengthening forcing cones. I like this better than rechambering since it removes less metal from the barrel. Toward this I want to ensure the remaining barrel thickness is adequate.

Do I need a proof law to keep me safe when I alter or buy an altered gun. No because I will measure the remaining barrel wall thickness virtually at every point in the barrels.
Would I send a gun for reproof at perhaps $100 per barrel. Yes, I would.

Mark
