I'm a weighing guy, so the idea of replacing the powder simply by volume doesn't even occur to me. But if I had to start tinkering with such an old gun, that's where I would start before trying to load BP. You need to get a 170 gr round to only 550 ft/s to produce the original load, which used 10 gr BP.
