[QUOTE="AZShooter, post: 1932152, member: 5219"] One of the fastest ways is to run cold water across the barrel with muzzle pointed down. I use to use the refrigerated water cooler at the range. But it had drawbacks. Couldn't do it if others were around as muzzle would have to point in an unsafe direction. Also only did this with a synthetic stock. Blew out any water in barrel channel. When the Canyon Del Oro wash flooded one year the cooler was taken downstream never to be seen again, A bunch of the members use a wet towel draped across the barrel. Some have a cooler with ice water for the towel. Others use a air mattress pump. The absolute fastest way which also keeps things dry is a CO2 system. A ball valve is installed with a rubber hose and a tapered tip which will seal against most chamber shoulders. A 20 lb tank is minimum size as smaller ones won't get very cold. You can get a barrel cool in less than a minute. I only use this system if I am working up a load and want to maintain ambient temperatures. I use it year round for that purpose. This pic shows the gauges I used before I switched to a ball valve. Drawbacks? The CO2 costs around $23 for a 20 lb tank refill. I own two tanks and go to a local welding supply store to trade the tanks out a couple of times a year. It will cool several rifles for around three or four range sessions.
