Routledge bore is a smooth bore for 22 rimfire rifles. It is most likely named after the person who originally came up with this type of bore. The barrel is smooth bored after the chamber at 22 caliber bore . Then appr 14 inches from the muzzle it spreads out to about.410 all the way out to the muzzle. Looking at the muzzle end it appears to be a mini shotgun. These rifles were made to fire 22 rimfire shot cartridges and were generally used for pest control or shooting at mini clay birds or crackers.
The Routledge Bore is an invention by Fred Routledge which consisted of the last 12"-17" of the barrel of a .22 bored to about 3/8" or .375" . This allows the tiny .22 shot payload to stop spinning from the rifling or in a fully smooth bore .22 to open smoothly in a sort of jug choke effect. The effect of the Routledge bore was to enable the .22 Shot cartridge to be effective at 15 yards or so on vermin,about 4 times farther than a .22 rifled barrel is able to deliver a useful pattern of it's tiny shot.
