Stock class mag freezing over. Im confused

IMO, what you need is an expansion chamber and a check valve installed between the expansion chamber and the 12g changer.

You'd need to have some way to degass the marker though.

Wrong you are. Because i would get up in 25+ range if I would wait for a while for it to turn to gas again........DO you have a mag? or tried this?

You MIGHT get 25 shots out of a mag on a 12gram IF you shot about 1 ball a minute in 80+ dgree weather. Mags are not that efficient, and yes I have tried it.

Expansion chamber with a 12 gram would be silly. The extra volume in the expansion chamber would waste some of your pressure, possibly a shot or 2. It would be like running a 12gram with a remote.

after it stops shooting unscrew your 12g, if no air goes PSSHSHSHHSH then your out of co2

Depends entirely on whether you have a check valve or not.

If no pressure was degassed from the marker, you wouldn't lose any shots. Except maybe from the first 12g.

I get 18-22 on my old school sydarms at 300 fps during the warm summers, I usually change 12g's after shooting 3 loads whether it needs it or not. At 265 (indoor) I get 22-26 full powered shots per 12g and change after 4 loads. During the winters, I get closer to your reported RoF of 13-15. Co2 just doesn't perform very well in low to moderate temps.

The secret is keeping them thoroughly lubed (I use KC trouble free for co2), keeping them squeeky clean, firing slowly (1 shot every second or so).

The aspect that has the most impact is the slow rate of firing, I use dual sydarms and alternate firing them so that I can keep the rate of fire lower per marker.

Single gunning and stuck firing faster then I want, then yes, the number of shots per 12g will be considerably lower. Basicly the liquid co2 isn't fully expanding (changing from liquid to gas state) before its being fired. Also, as the chamber cools down and starts to freeze over(usually quite quickly under rapid fire), your efficiency will drop.

First off, I am shocked you can gt a sydarm to shoot at 300fps. Second, those numbers are unbelievable. I have never gotten anywhere near that many shots with my Sydarm or my pump mag.
