In a gas pistol, with heavier weights the BB in in the barrel for a longer time, allowing for more gas expansion and more energy transferred to the BB. Hence why I only shoot 10 FPS difference between .2's and .28's on my 229. Make sense?

That makes sense. I'll try running my 416 thru my chrony with .2s, .25, and .28s tonight to try to gauge the difference.
