[QUOTE="Mike Matteson, post: 2572924, member: 101791"] CO2 cooling system: Fitting a ball valve is all is needed. A 20lb tank is minimum. The hose should be tapered at the chamber end for ease of sliding it into position. The CO2 is released with low flow. It only takes 20 - 30 seconds to reach ambient temp unless the barrel is quite hot. Feel the barrel is approaching close to the same temp at the scope, the CO2 is turned off. It will continue to cool from inside out. Many at the range have adopted this system. Need a bore guide for the uses. (Run your tubing from the CO2 tank into an un-ported Delrin bore bore guide for ease of application. This was copied from another location. Just where I don't remember. [/QUOTE]
