Thanks makes perfect sense to me now! What the caliber, velocity and shot count? 13ci ? What regulator?

Must be nice to be less dependant on temperature.

You might be able to get a higher shot count playing with striker wieght and striker spring tension without affect your velocity.. Wil quiet down the qb79 also.

to be honnest I like CO2 more then hpa but I'm going for 900fps to 980fps and that would make it hard to get at with CO2.

I get alot more shoots with a full 9oz tank then a 13ci hpa tank.

Good luck with your goal. 850-875 will give the most accuacy most likely. Also don't expect the gun to like the same pellets when powered up. It does nto always change but can.

My m48 .177 shoot amazing groups at 50 yards @930 FPS when I replaced the spring to the vortek PG2 and they were doing in the 970's they would no longer group as well. A small change in velocity can make a big difference for some pellets.
