I am interested as well. I just bought one used a week ago and have only fired a few rounds. It's an older BP rifle in 50 cal but looks great. I understand based on the serial number it was imported in the mid / late seventies. I didn't get a manual or any info. In addition to general info on how they shoot - what's the twist (I see references to both 1:24 and 1:48 on various web sites), load info, max. load of ffg, patched balls or conicals, thread for nipples, sites (is one for short range and the other for long range or is there one for each barrel), how do you adjust for elevation? Thanks.
