John,
These are .028 at their thinnest spot 2/3 way down the barrells. Excellent bores, .027 choke each barrel so add .0135 to the thickness at the chokes, .615 bore, never refinished outside or honed inside, 0 frame, not cut. I'm not concerned with their safety. They have been shot for 110 years. I just don't want 12,000 p.s.i. and want to load my own for $5.00 a box instead of $12.00.
