yes, halo B will end every chop (caused by the bolt) if ur using big bore paint (maybe .69 or greater) might be causing ur "chops" this is b/c the balls could be to large for the barrel, and shatter when they hit it, since they can't fit.
need more info. are the balls blowing up in your hopper or what? If it's just a regular chop then get a faster hopper(EGG, HALO B) or possibly a new bolt. Kingman makes an ACS(Anti-Chop-System) bolt for $40.
