All of this is fine but to what avail?
Mass time acceleration may equal force but speed is a function of the force applied over time.
So in theory a larger force for a short period of time can give the same shot speed as a lesser force over a longer time.
We know that in a 12 ga. PB can produce 1200 ft/sec. at far less pressure than other powders. But I have yet to notice any difference with my heavy 12 ga.
My light weight 20 ga feels quite different with factory shells vs the same speed with my hand loads.
Okay, so what does all that mean?
It means that there will be more misshapen pellets in the small gauge load, as was states in Miller' original post. There are still some on this board who poo-poo that science. I even posted a link a couple months ago mentioning that I had spoken to Tom Roster about this and he told me about research he had done absolutely proving it. It's easy to find with a search. Misshapen pellets degrade the pattern, all else being equal.
