25ml sprinkler valve and 40 ml barrel loss of POWER ?

Unread postAuthor: chicagobears10 » Fri Jan 18, 2008 1:47 pm

Im building my second potato gun and i have already got my 25mm sprinkler valve finished because i was goin with a 25 mm barrel

Now i want a 40ml barrel but i am wondering if there will be a substantial loss of power.

Thank you

Mabye ml is the volume, still, I've never heard of a sprinkler valve measured in ml.

Clarify, kthx.

ya if were talking mm as in millimeter, then you would lose a little bit of power because you would need more air to push the projectile out the barrel. (bigger barrel= bigger projectile)

Well yeah there will be loss of power, depending on a few things.

No, there will be no loss of energy, you'll probably actually gain power because of the larger bore, but assuming you'll have heavier ammo, you will see lower velocities for the same energy.

Does that thing kinda look like a big cat to you?
