Air Efficiency question.
 
I just recently aquired an SS-25, not sure of the year, which is my first CCM Marker. Don't worry, I will post up pics in a day or so. So my question is, what is the range of the amount of shots that I can get with a 12 gram, a 13/3000 tank, and a 45/4500 tank? I have a friend who religiously plays with his CCM pump, not sure of the model, but he tells me that he only gets 600 shots from his 45/4500. I was wondering if I could increase the efficiency by changing out the valve to either a Palmer's LT Valve or an AKA Tornado Valve, or by fine tuning with a spring kit. The only reason why I ask is that I typically get about 350 to 400 shots per 1000 PSI with my Viking that is using a 45/4500 tank and a Deadlywind Barrel.

600 shots sounds like a load of bull... I get over 1,000 with my Droid and its a SPOOL valve...

Well that is what the customer said and you know, the customer is always right (even if they are wrong :rolleyes:). You also forget that the Droid is the most efficient stock spool valved marker ever made. It only took like 6 years to figure out how to do that. :ROTFL:

Sniper pressures and spring settings affect efficiency quite a bit.

Indeed. I have heard that CCM guns are not overly efficient due to the springing for smooth pump strokes. 600 does seem a tad low, but not entirely impossible (again, based on what I have heard).

Actually, 600 is probably about right.

Source, my S5.

CCM valve spring is super weak and very inefficient. Go to a stiffer valve spring; you'll have a harder pump stroke, but near double the efficiency.

I have a S6 prototype and get more than that out of mine now that I turned the reg pressure up. The prototype is mini'd and TF suggested I try it at 450-500 and it has made a drastic difference. I use a 68/4500 at scenarios and got between 1200-1500 at the last 2 day I went to.

make sure the regulator is sweetspotted

I havent played with my ss-25 in a while but I seem to remember getting 150-200 shots from a 13/3000
