[QUOTE="scope-eye, post: 2044033, member: 21274"] Yes both of those are huge contributing factor, look at AI case and a regular one a 25 deg neck will flow smoother imagine you were pouring water though it. And as far as the free bore is concered all that pressure from the spent powder is trying to exit through an already reduced passage, "neck" then it is met with bullet resistance from the short freebore which adds insult to injury don't forget the bullet has started to move forward before all the powder is all burnt. like I said the funnel is overwhelmed.
