A bull barrel is a type of gun barrel that does not taper outward, making it completely cylindrical. This makes the barrel stiffer, which reduces the amplitude of the vibrations in the barrel created by by the sudden increase of air pressure in the chamber when the gun goes off.The point of the bull barrel is to reduce the negative effect these vibrations have on aim.or pistols like the Ruger MK III and other small guns that use bull barrels, the vibration-dampening effect is less important, if it factors in at all. In guns with shorter muzzles like pistols, the bullet doesn't spend enough time traveling through the the barrel for it to be overly affected by the vibration.
Consistency means accuracy. A third benefit of a bull barrel is associated with its weight. Being heavy, it tends to allow the rifle to recoil less, and that helps the shooter cope more effectively. This is especially important when talking about the larger calibers that kick a lot.hat throws the AR shooters is that there is a specification for a heavy barrel for an AR-15/M16, and they mistakenly think it applies to all other firearms. This barrel is sold as an AR-15 bull barrel. It has flutes, but theyâre not a requirement for a bull barrel. An AR heavy barrel would be much thinner than this.
