I know a few who run ambient temperature water (not cold) through their barrels with no ill effects. Personally we have always taken 3 rifles each with us in order to let them cool slowly. Opening the bolt and sitting the rifle with the barrel upwards seems to dissipate the heat a bit quicker. My eyes usually need a break anyway after a bit (I start seeing 3 set of crosshairs) so it isn't an issue for me. Like I said, I know folks who pour water through their bores but I haven't had the need. They have been doing it for years with 204, 22-250, and 220 swift guns.
I've done it. No issues. Didn't overthink it, just opened a bottle of water from my pack and slowly poured it through the breach. Rifle is a 20" 223 and with over 8000 rounds on it will still keep just about any load put through it under an inch @ 100yds.
I have heard of one person buying a "FISH" tank pump, getting a small piece of hose, inserting it in the throat so that it seals around the lands, and turns it on.
He claims it's the fasest way to cool a barre down with NO mess.
I am going to try this.

Used that exact set up last year Ackleyman pdoggin. Pretty sure it was you that recommended it. Almost 100 degrees and shooting a 6-284, I needed it. Worked ok, not as good as I would have liked but it was really hot.
Bryan,
Where did you get that and how much did it cost????

Is there any reason I can just insert a long funnel into the chamber and pour water through it ?Here's what I have come up with..since I'm in the compressed air industry I have access to fittings etc.
