In my study since acquiring an H&H double I've run across three different proofed bore diameters for the .50 BPE guns.
So far I've read about guns having 38 gauge, 39 gauge and 40 gauge bores.
Can anyone actually tell me what were the industry standard bore and groove diameters for these three different gauge barrels? Assuming there actually an industry standard in 1885.
