Most flutings on rifle barrels and revolver cylinders are straight, though helical flutings can be seen on rifle bolts and occasionally also rifle barrels. This is most often done to the exterior surface of a rifle barrel, though it may also be applied to the cylinder of a revolver or the bolt of a bolt-action rifle. Construction įluting is the removal of material from a cylindrical surface, usually creating rounded grooves, for the purpose of reducing weight. This was because manufacturing defects such as air bubbles trapped in the metal were common at that time, and played key factors in many gun explosions these defects made the barrel too weak to withstand the pressures of firing, causing it to fail and fragment explosively. Įarly cannon barrels were very thick for their caliber. During the 19th century, effective breechblocks were invented that sealed a breechloader against the escape of propellant gases. The later-invented breech-loading designs provided a higher rate of fire, but early breechloaders lacked an effective way of sealing the escaping gases that leaked from the back end (breech) of the barrel, reducing the available muzzle velocity. Įarly firearms were muzzle-loading, with the gunpowder and then the shot loaded from the front end (muzzle) of the barrel, and were capable of only a low rate of fire due to the cumbersome loading process. Bronze and brass were favoured by gunsmiths, largely because of their ease of casting and their resistance to the corrosive effects of the combustion of gunpowder or salt water when used on naval vessels. Early European guns were made of wrought iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings and then welded into a hollow cylinder. The Chinese were also the first to master cast-iron cannon barrels, and used the technology to make the earliest infantry firearms - the hand cannons. However, the early Chinese, the inventors of gunpowder, used bamboo, which has a strong, naturally tubular stalk and is cheaper to obtain and process, as the first barrels in gunpowder projectile weapons such as the fire lances.

Compare this to the straitline barrel that is rifled, it works great because a backspin actually works for paintballs where rifling just doesn't.A female worker boring out the barrel of a Lee-Enfield rifle during WWI It does effect the flight trajectory of your ball and it can be very accurate doing it. To answer your second question 'Does it actually do anything?', the answer is yes.

Anyways, someone made a writeup on how to calibrate this very picky barrel. Too much speed and it will break the ball, too little and it won't be accurate. This barrel is also extremely sensitive to ball speed. To get the same velocity as a regular strait barrel, you need to set the regulator higher, which means its less efficient. Now because the barrel relies on friction to create this spin, the exit velocity (barrel velocity) is significantly slower than a regular smooth barrel.

The flatline barrel is curved and is actually rough inside, unlike most paintball barrels, to create this spin. Think throwing a fastball in base ball, the ball has a back spin and actually curves up because of the pressure differences between the bottom and top of the ball. The Flatline barrel works based on the Magnus effect.
