The left barrel was made to be used with a single projectile (bullet). If it had been made after proof laws were implemented, the left barrel would have been proofed as a rifle. Early on, brass cases were available in bore sizes from 40 to 76 mm long and even longer. The right barrel was made to shoot shot; the straight grooves were thought (hoped) to give room for black powder fouling. I have recently read the purpose was to concentrate the shot during "pre choke" days, I can't say what they were thinking, but the utility for this is doubtful.
