Lovely job!

Sad to hear about the barrel blow up. Was that using solids?

I have and have had a H&H double from 1906. It was recommended by a double rifle expert that using solids puts too much pressure on the barrels and that I should use the Woodleigh Hydro bullets as they are lower pressure and made of the same material as the jackets of SN and FMJ bullets, without the steel of a FMJ of course.

I think that this has been borne out by some pressure testing.

Some of the Hornady stuff is fairly quick too..
