Ok I have Another dumb theory,
When Filling A C.C With Spray have the potato at the top of the barrel then put the cleanout on . When you press the potato into the barrel it compresses the mixture by decreasing the distance the gas can occupy
Sorry i know my theorys are way off
Compression Theory
Nope this has been mentioned before and is pretty common. You do have to adjust your fuel ration if you're using a metered cannon

Note that the potato might shove back up half of the barrel when you stop ramming it.

If there was any blowby then you probably defeated the purpose.sprayandplay08 wrote:when i did that there was a small amount of blow by
A very tight fitting spud in a 2" barrel might seal well enough, and have high enough static friction, to get the chamber up to ~10 PSIG. That would be a ~1.7X hybrid. If you calculate your fuel ratio for the chamber+barrel volume, partially load the spud to seal the system, and run the fan to mix the fuel, you might be able to get a small hybrid ratio by shoving the ammo as far down the barrel as you can without having it leak or immediately pop back out the barrel.
