The 2 most likely options are that the bullet is seated out too far, and therefor hitting the rifling in the barrel, or the loaded cartridge isn't crimped enough. If the cast bullet you are using has a shoulder, no more than .010" of the shoulder should be above the case mouth. The crimp at the case mouth should measure .378-.379" on a loaded cartridge
