Barrel coolant

[jon lynn]

I saw an advert in one of the gun rags for a spray. After your barrel heats up, just spray it down your barrel to cool it. It was from the makers of the canned air for PC's.......any-hoo............

Couldn't spraying a cold chemicals down a hot .308 barrel cause damage to the barrel or rifleing?

The reason I ask, when I start pulling the trigger here, it would pay to have something like this, because shooting ranges are timmed here (ask Dom), you don't get a whole lot of time to bench it. One of the places I go lets me have a full hour, but all the others in my reigon only let you get 20 minutes a pop, for a price too!

So would this spray be a benifit or a hazzard?
