What do you have against dump chambers?
The simplest way to say it is that the entire dump chamber volume is added to the pre-expansion volume for efficiency purposes. Sealing dump chambers pretty much just stems the bleeding from the system, you ideally always want to meter out a set amount of air to the ball and let it expand (entirely post valve). Not to mention you lose recharge from the reg.
In the age of all day air it doesn't really matter.
except in terms of recharge.
i have herd, only herd, many spools have issues with recharge. never had a chance to test them myself.
another reason for looking at efficiency as a good thing even if we usually use free all day air, is two fold.
1. a more efficient gun can use a smaller, lighter tank.
2. tune for efficiency, gain consistency.
and by that i mean inefficiency is caused by chaotic flows, flows that are more chaotic are less efficient, and by their nature, less predictable and harder to normalize. this means that by the properties of fluid mechanics, less chaotic flows means more efficiency and also more predicable and more normal flows.
so, within a type of gun, or a gun design, making that particular setup more efficient makes the fluid flow more normal, makes it more consistent.
now, thats not to say that a more consistent gun is more consistent then a less efficient gun. but if we take one gun, and run it inefficient, we should see it shoot also less consistently. the transverse is also true, a more efficient operating method or tuning for a gun should make it more consistent.
