[QUOTE="AZShooter, post: 1692997, member: 5219"] Interesting thread. While I don't get my barrels hot I use CO2 to get the barrel back to ambient temperature to continue load development. Saves a ton of time. Use a 20 lb CO2 tank minimum. When I first made it back in 2006 I used a regulator that allowed the flow I wanted. Not all regulators will work. This one does: Prest-O-Lite R36-50-580. I finally wore out the T handle threads and went with a ball valve. The rubber hose was 3/8" OD. I tapered the tip with a knife so it would wedge into the neck area of any rifle I use from 6mm BR to 375 Taylor. As for using the CO2. Hold hose in place while you open up tank valve then rotate T handle or ball valve to get a mild flow coming out of the end of the barrel. [LEFT][SIZE=14px][FONT=verdana][COLOR=rgb(20, 20, 20)]There are now five shooters that copied this idea. All of us that use this system to keep the barrel at ambient not for cooling a super hot barrel. With some magnums I will use it after every shot or every two shots. It even worked on a Rem 700 ultimate muzzle loader by putting the hose far down the muzzle end and gently blowing air through breech plug.
