A gentleman, much brighter than I, had rigged a computer "cooling" fan to a PVC tube which fit over the barrel. He had it powered by a deer feeder battery. After he shot a group, he would set the fan over the barrel and let the fan "cool" the barrel. it was genius

I've heard that there are peeps out there who don't have guns 2 and 3, only #1. I do not believe in monogamy with my guns.

Doesn't sound hard to do at all.
Get a magazine and rip the internals out. Cut a hole in it the size of the pc fan. Mount the fan. Rack the magazine and plug the fan into a 6 volt feeder battery.

I'm sure that there are folks on here that know way more than I. I've got to believe that rapid heating then equally rapid cooling to your barrel is not good for your barrel.

I don't think the temps are high enough to matter.

It's not a rapid cooling...most of these devices are just making certain air is moving down the bore. Which in turn will cool it faster and especially faster than no outside air being pushed down the bore. I've always set them upright when I could thinking the hot air rises will pull air into the bore...I know they cool quicker with bolt out and positioned vertically then sitting horizontally. But again, not near as fast as a fan blowing cooler (think ambient) air down the bore.

I'm sure that there are folks on here that know way more than I. I've got to believe that rapid heating then equally rapid cooling to your barrel is not good for your barrel. Cooling won't hurt it. Ten rounds in 90 seconds will hurt it, but cooling it back down to shoot again, won't. I've wrapped ice water soaked chamois around barrels so that I can move on with load development. I need to build one of these air coolers though.

Is there an ideal temp to get down to before firing again? And if 10 shots in 90 seconds will hurt the barrel (I'm assuming this varies per cartridge case size) then what is the upper limit on heat. I love watching Iraqveteran88's torture test videos, but what is the threshold for preserving accuracy?

I have a hunting rifle which shoots a 140gr VLD @ 3000, It has a number 4 contour barrel. The builder said to me, my rifle is built as a "hunting" rifle and he wouldn't recommended me shooting it in a timed rifle match. RE: F-Class Open.
