Theoretical maximum shots per 12g?

Using an ideal marker theoretically how many shots can a 12g give under normal conditions?

Do you have any limitations on operating system? IE: semi or pump/single-action?

I've heard of Redux's getting up to 40 on a 12ie, which is the highest I've heard of for just about any marker.

For a semi, I've rarely seen anyone report over 30. I would wager that with absolutely perfect cartridges and a perfect gun, you could probably add 5 shots to either count for pump/semi. But the money required to get any marker to such an ideal state would probably be highly counterproductive.

My old PPS- tuned PMI-1 would get at least 40 useable shots if I didn't rush it, from a ported barrel. I think DSA reported 47 from his tuned Dux.

Team tests of LAPCO Grey Ghosts regularly produced 45 to 50 "usable" shots.

That means that the ball came out of the barrel at sufficiently high velocity to travel towards the other team at a threatening speed. In other words - fast enough, noisy enough that someone being shot at would believe that it could hit and break on them.

"Good" shots - 35 to 40, using Leland 12-grams.

Superior shots - 25 and under. SOP was to dump the 12 gram after 25 anyway.

"Wait for the 'ouch!'" 1 to 5, after supercharging, lol. Sixpak+ had a check valve....

I am thinking if you really wanted to find the theoretical, not real world, maximum shots per 12ie, you would set a system up where you could release tiny, metered amounts of CO2 directly onto a ball sitting in a barrel. Also this way we could control the barrel length as a variable, as well as the distance CO2 is allowed to expand before it hits the paintball.

I believe we lose a lot of CO2 from inefficient seals/junctures in the valves and air transfer paths of our favorite pump guns. A member on these forums who I believe has done extensive testing with 12 grams and valve systems is 3022. Try shooting him a PM and directing him to this thread .

An electro would not be more efficient than any pump. It uses a solenoid to control the flow of air, but air is still used to operate a pneumatic ram. When your hand is that ram..you save efficiency.

I agree with Ironchef though.

I have tested this out years ago (2004) with Buzzards and Phantoms and in 2007 with a Grey Ghost . 40+ at 250 FPS or better was the benchmark for VSC nelson guns. A back bottle stock class setup offers 3 to 5 more shots. My PPS valved and tuned sheridan is good for 32 to 35 under the same conditions.

This was with a barrel to paint match that some of today's folks will describe as "underboring" on a day where the temp was 75 to 85 degrees. Time between shots was about 20 seconds.

My policy is to change 12 grams at the 30-32 shot mark.

I've seen 45 good shots on a cocker. Not even a sniper. I was shocked.
