Re: Rifle barrel twist - can someone explain?

Real easy, lets say a 1 in 10 twist, this means that for every 10 inches of barrel the bullet will rotate 1 time. If the rate of twist is 1 in 12 the bullet will rotate 1 time every 12 inches giong down the barrel. This increases or decreases the spin or rotation of the of a bullet. Some bullet weights need more spin in a certain caliber some need less. Does not sound like much but when the bullet is traveling at 3000 fps its spinning very fast.
