Shooter Step In Please!

[onebadvet]

I was at the range today, and I notice shooters with fan to keep there barrel cool, to keep accurate hitting the target.
I was wondering what shooter are using to keep there barrel temperature down
Saw shooter using this type of fan.

Isn't it traditional to pee on your barrel if it gets too hot? That's what the buffalo hunters supposedly did ...

They also peed in the barrel and let it stand overnight to loosen up all the lead and powder residue. Made it a lot easier to clean in the morning. Just goes to show you - even a small garden hose can be a pretty handy thing...

Multitask:

Right now I use a fan, has in the picture my set up, others were using a cooling fan that went inside the barrel. Also use the fan to keep me cool, in S Fl it's in 90S.

I don't have any trouble maintaining 1/2MOA or better with my precision rifle and I don't use a fan. That's taking about 1 shot per minute and only 5 shots every 15-20 minutes.

I don't have the patience to work on shooting that requires precision at the level where a fan would make any real difference.

That one from Amazon looks like it would work for you. Let us know if it really makes a difference.

A Beagle club I used to belong to had a old tractor that had side draft carb, in the winter it would freeze up, I would stand on the other side of the hood and pee on the carb to thaw it out, if it was real cold 3 or 4 of us would have to pee on it, we must have looked pretty stupid. [emoji1]

It seems all you guys like to pee on gun barrels, sorry wasn't a great white hunter, I only kill paper at the range, with bunch of others, and peeing is out.

 

[andy52]

Peeing on barrels ain't nothing new gunmakers in the 1700-1800s would pee on the outside of new barrels for several days to rust finish the exterior, card off the surface and start all over again until the desired finish was obtained.

These don't start shooting good until the barrels heat up.

Good grief. A fan will not cool a hot piece of metal, because they don't cool the air. They just move it from one place to another. Cold or hot, the temp stays the same. Fans make people feel cooler by moving air over their skin. Metal doesn't have feelings.

Now you're just being insensitive.

Ahem ... air-cooled aircraft engines?

My understanding of physics is sadly minimal, but as far as I know, it works not by cooling the air, but by way of the air absorbing heat from the hot surface. Thus, cooling fins. More air flow, more cooling. So a fan should have an effect on a hot barrel. Or... ?

But, the hot metal begins losing heat because of the temperature differential to the ambient air. With no air flow around it, the air in contact with the metal stays at a higher temp...with the help of air movement (the fan) the zone of air in contact with the metal is constantly "torn away", the temperature differential is maintained at a higher level, and the metal cools more rapidly.

Then why doesn't my shop fan reduce the temperature of my shop?

Because you are just moving air around a space, not removing energy (heat) from a hot item.

 

[Muss Muggins]

My shop is a hot item. I'm sorry, but if there is any benefit to a fan on a hot piece of metal, it is minute. I plan to test my WAG by putting a thermometer in front of my shop fan and moving my shop fan out on the apron tonight . . .

I didn't realize that Chevy made tractors.

Now that's two different arguments.

Your shop is indeed a hot item, which is why your fan would cool it if you employed it to remove the heat from it. Set it in an open window blowing OUT, and have another window or door open so you get air flowing in. Assuming the outside temperature is lower, you will cool the shop.

I'm in agreement with you about the minimal effect of these little fans on heated steel. But that's a matter of efficiency, not the principle. For efficient air cooling, you need maximum surface radiating the heat to be absorbed by the air flow; that's why you have the cooling fins on motorcycle and aircraft engines that rely on air cooling. And a little plastic fan blowing around a dense metal tube with a thin profile doesn't compare to the airflow you get over large surfaces at 120 mph.
