This is how I figure.
Gas behind a heavier BB has more time to expand and exert its force onto the BB, this in turn give it more energy than it would receive had this been done in an AEG.

Apparently this knowledge as not as wide spread as I thought it was on ASC, guess we need to do some more work on disseminating this very important information.

Actually, tons everywhere if you google :P
Tons of information on here too. There is a reason there are a few of us pushing game hosts to set ENERGY limits and chrony for energy and not FPS, ESPECIALLY with gas guns.
This method is being followed for Nightfall this year.

Yes, it is that high. There is a significant increase as seen above.
