Are back-bored barrels better?
Better Patterning Back-boring reduces friction between the shot cup and the bore for increased shot pellet velocity, minimized pellet deformity for more uniform patterns and reduced felt recoil.
What is a back-bored shotgun barrel?
A back-bored barrel is a shotgun barrel that has the bore diameter increased more than standard specifications resulting in more consistent patterns and increased shot velocity that helps you hit what you’re shooting at and believe me I need all of the help I can get.
What does Overbored barrel mean?
A back-bored barrel is a shotgun barrel that has a bore diameter increased beyond maximum specifications. Increasing the bore diameter of a shotgun barrel greatly enhances its performance. A larger bore diameter reduces friction of the shot charge against the barrel wall.
What is a backboard barrel?
A back-bored barrel is a shotgun barrel that has a bore diameter increased beyond standard specifications. Increasing the bore diameter of a shotgun barrel greatly enhances its performance. A larger bore diameter reduces friction of the shot charge against the barrel wall.
What does lengthening the forcing cone do?
By lengthening the surface, several great things are achieved: Velocity is increased by reducing the sudden friction encountered with a short forcing cone. Felt recoil is reduced because the reduced friction allows the shot load to smoothly enter the shotgun bore.
How much does a gunsmith charge to cut down a shotgun barrel?

What is the ID of a 12 gauge barrel?
The internal diameter of a 12 gauge shotgun barrel is therefore equal to the diameter of a lead ball weighing 1/12 pound, which happens to be . 729″ (Or in British: Bore.)
What does choke bored mean?
Chambers’s Twentieth Century Dictionary. n Choke-bore the bore of a gun when narrowed at the muzzle so as to concentrate the shot: a shot-gun so bored.
Do Rifles have forcing cones?
No it isn’t. Shotguns have a forcing cone. Rifles and Auto pistols have a throat to ease the bullets entry into the rifling which is no different than a forcing cone. The only difference with a revolver is the jump from the cylinder to the barrel which is why they have a 9 1/2,11 and a 18 degree entry angle.
Does lengthening the forcing cone in a shotgun reduce recoil?
In most production shotguns this forcing cone is very short and at a very steep angle. We lengthen the forcing cone to 3 inches and and polish it. By lengthening the surface, several great things are achieved: Felt recoil is reduced because the reduced friction allows the shot load to smoothly enter the shotgun bore.
What kind of barrel does a Browning Citori use?
Some newer 12 gauge and 20 gauge Citori models have back-bored barrels. These are barrels with slightly larger bore diameters. Their purpose is to improve shot patterns by reducing the friction of the shot charge on the barrel wall, while also reducing felt recoil. Models with back-bored barrels use Invector Plus choke tubes.
Why does a shotgun have a back bored barrel?
Most shotgunners are familiar with the phrase back boring. Often it is advertised as a way to reduce recoil and improve shot patterns. A shotgun with a back bored barrel has its bore opened up to a larger diameter than when it was originally manufactured. A quick caveat about bore size in shotguns,…
How big is the top of a Browning pistol barrel?
Barrel lengths can be purchased from 26 inches for skeet shooting to 32 inches for sporting clays and trap shooting. The top barrel has a vented rib attached by soldering for the entire length of the barrel tube.
When did the Browning semi automatic shotgun come out?
It was part of the Browning Arms Company line from 1955 to 1969. Patents were filed on a 45 caliber semi-automatic pistol. It served as the official United States military sidearm for almost 75 years. Filed patent on a pump shotgun that would be marketed as the Remington Model 17.
