I put some time behind the Chronograph with my new Sterling. These reading are after I've shot about 500 - 600 paintball's through the gun with this valve.

time:
Temperature: 70 F
Paint: RPS Premium, 2 weeks old
Size: .679 (using my Freak Insert for sizing)
Co2 brand: Leland
Co2 size: 12 gram

Along chrono numbers and thier simple KE re-calculation, it is that not better overall efficiency than my heavily tunned Sterling Bronze, or the oldironmudder Sterling with reg, but you having better results than oldironmudder best setup without reg... and the 366 J are actually pretty high for non-nelson, "amateur" tunned paintgun (PPS Superstocker has "only" 380 J). With the 30 consistent shots above ~270 fps... there is in reallity no need of further efficiency tunning for practical paintball.

Thank for the data and your input.

I did pick up a Palmers Male Stabilizer for down the road "tuning". After my session last night though behind the chrono I felt the same way, no real need to be worried about how efficient my gun is on 12'ies, besides this gun is pure "Bone Stock" with these readings.

On the other side, the economy & power are not the only characteristics. Efficiency does not not only improves the "kill abilities" of the marker, but it is somewhat even question of "style". Maximally effective SC markers having somewhat unique feeling. Because they are more efficient, they having lower kick and sound signature that other markers.

Didnt use my Sterling today but I got some video/chrono time with it. I will upload the videos later. Somewhere around 40 shots above 220fps. < Just to give you an idea. This is also in the cool shade all day & not out in the sun or in my hands.

That is the exact reason I bought a reg for my STP SC. I cant wait to put mine to the test after I sweet spot it.

Great video oldironmudder.

Cool, I have not been on the boards lately. 3022 I appreciate the detailed calculated KE value of R018 when she is shooting well.
