If the hole through which the BBs have to pass to get to the ball valve is the same diameter as the barrel, then there will be a BB in place to block the flow until it is allowed to move when the ball valve is fully open, so air losses will be minimal.

Besides, even after the valve is opened you'll be dumping air for at least a couple seconds. The 1/10th second (or whatever) that it takes to open the valve isn't going to be a significant factor in the air useage.

Ok, you win...
Now you just need to make it work with a nice trigger, rather than a ball valve, so that it is usable in real airsoft situations.

Do not look back, and grieve over the past, for it is gone;
Do not be troubled about the future, for it has not yet come;
Live life in the present, and make it so beautiful that it will be worth remembering.
