Why does my railgun seem to shoot the spear much faster and straighter than my standard gun?
On a railgun there is no sag in the middle of the spear because of the rail supporting it, and the length protruding out of the muzzle need only be short, therefore the spear weighs less. The drive ratio of the rubber is now much improved because the length relation of barrel to spear has increased; therefore more speed is attained without increasing the rubber strength. Another reason the spear is faster is because the spear does not wobble because it is supported level before being fired, and remains straight once momentum is achieved. Wobbling of a spear develops with a standard gun when the spear has a slight sag in the middle along with sag at the end. The moment the trigger is released the spear tends to “buck” creating a wobble when fired from a standard gun. This obviously creates more friction and therefore slows the spear down a great deal.
