I will be shooting low pressure 2 1/4" 7/8oz loads with Green Dot powder in my English damascus barrelled guns, thank you.
I do not want my barrels subjected to the extreme strain of Proof House loads.
Was there not a big fuss recently about over-strength British proof loads destroying brand new Purdey barrels, Lagopus I think you reported on that? Who would compensate me if my irreplaceable 1870 barrels were ruined?
As an aside, a gunsmith here gave me a real cheap 1880s Belgian 12 double ga hammer gun, marked with a mythical English maker's name.
I wanted to burst the barrel as a demo for the 12-20 ga dilemma for Hunter Ed classes.
Five times I loaded a 20 ga shell in front of a 12 ga shell and fired it, all I got was a slight bulge ahead of the chamber.
With an accidentally 12/20 scenario, modern Brazilian single shot hammer gun, chamber split open and severely injured the arm of the shooter. Just my 2c anyway, I'm not asking you to shoot my Damascus guns and here in Canada I do not see how it could be an insurance issue.
