I would say between 1/2" to 1"


Because it has traveled approximately about 2" at that point and is exiting the forcing cone. If you remember your fluid dymanics you would know that pressure drops when matter exist a nozzle. It also increases velocity, but good luck measuring that inside of a gun barrel. I wish we could.

I don't know. My position is that it does to some, as of this point, unknown degree. As far as I can tell, your position is that it has no effect on it.



All of those things are not exclusive of this topic, nor can they be excluded when discussing peak pressures or time curves. My contention is they all have a factor to play, which sets shotshells apart from the muzzleloader.



I'm not sure. You seem to be very disagreeable to the idea that it has any effect. I'm simply stating it must have some, which I don't think is a reach.

I know from reading your many posts over the years you seem to have made contacts with experts in this field over the years, and have access to testing equipment most of us do not. This might be an interesting experiment to take on if you are truly curious about it. However, I would agree the outcome of those tests would mostly be academic without much real world demand, i.e. pressure curves in muzzleloading vs breechloading shotguns . I think this one will most likely stay in the realm of theoretical debate, probably for good reason and not be worth the time or money.

Now coming up with experiments to test the effects of different forcing cone shapes/lengths in regards to breech pressures...that might be a different story

Thanks greenerguy. Hadn't thought about "Stonehenge"

Ah Stonehenge! Read About him for years but never read his book. Thanks for that link Drew, have downloaded it to my computer, just haven't had time to read much of it yet. Will do so soon.
