If that was happening then the bullet diameter was way too small for the barrel and would never be accurate. A correct fitting bullet will engrave deep into the rifling as soon as it enters the rifling and should never slip at low velocities. It is possible to strip a cast bullet by driving it too fast, this will leave the barrel in a mess and once again accuracy is gone. My cast bullets work well at around 1300fps, hard cast bullets can be pushed faster but you are better using a gas check which adds to the cost.
