First & Foremost let me say, I am not advocating it, but I fail to see the reasoning behind;; If I stick a high brass "Express" load (max pressure 11.5K) in a gun & fire it with no damage, why this would result in possible irrepareable damage while if I pay $300.00+ to ship to England & they fire a 16K+ pressure load through it none will occur. The theory behind proof is if it holds up to one shot of a given pressure it should hold up indefinately to a pressure of about 2/3 that intensity.
