Testing: Marker Efficiency

Look at this shit.  18 posts, not a shred of fucking verifiable, decent data.  Just a bunch of half-cocked suggestions.

i want a very efficient marker help me out

I don't know why this is so fucking hard (unless my physics assumptions are off).

All these shitheads that do "efficiency" testing are just looking for an excuse to shoot and dump paint; they don't give two shits about science or data.

After the testing is done, they still haven't produced any sort really usable metric, aside from a rather non-useful datapoint like "x number of pods off a 68/45".

Here's what you do.

Take your gun.  Make sure everything is in a steady state as far as temperature.  (No hot fills!)

Record all conditions -- paint used, barrel/bore used, ambient temp, etc.

Chrono it.

Remove everything from the gun except for the tank.

Weigh it.

Reassemble the gun.

Take X number of shots; however many it takes to get enough of a weight change to show up on a scale.  Depending on the quality of your scale, maybe it will be 50 shots, maybe it will be 100 shots.

Remove everything from the gun except for the tank again.

Weigh it.

Divide the weight difference by the number of shots.

That is the amount of propellant you use per shot.

THAT IS THE FUCKING NUMBER WE NEED.
