Cooling Barrel With All Thread Rod.

[RVTECH]

How about a can of chlorine free brake parts cleaner?

Stuff comes out of the can nearly freezing.

Fill the barrel with the little red hose attachment on the spray nozzle, give it a minute or two, dump it out and it will evaporate in a few seconds.

 

[DLS]

Canned air and brake cleaner cost money. Refreezable ice packs and air are essentially free of cost.

Likewise, I let mine cool by themselves which takes patience. However, I'm not as concerned as others seem to be about minute amounts of accuracy.

Everything I own is far more accurate than I am. I'm not a Competitive shooter.

Letting the barrel cool on it's own would create the least amount of fuss. I am trying to get a lot of rounds in during my range trips and worry about accelerated wear by shooting the barrel too hot.

Take it back to your vehicle and turn the AC on…

Or bring a battery operated fan.

The air over an ice pack absolutely works.

This is one of the craziest things I think I've read recently.

Nevermind, make it as over complicated as you can and report back.

The "worlds tiniest" air blower with some 3/8 surgical tubing both from Amazon for less than 20 bucks moves some serious air thru the bore. Yes, Ive built one of these and it works.

Bring multiple guns, unless you're trying to do a burn down test then you don't want to cool it anyway.

You could also fill a length of 6" pvc pipe with water and just dunk them.

If the rod trick doesn't work, I will give this set up a try.

As is all of it.

Just go shoot and not concern yourself with it.

Do you really believed you are going to shoot so much as to wear out a barrell?

If it's a slow range day I could hog a couple of benches and bring a couple of rifles. If it's a busier day, I don't want to be that guy.

Dunking rifle barrel is a good idea but would be frowned upon by RSOs.

Yes.

Edit: maybe it's an irrational fear. I guess I could just ignore the heat issue and shoot until the stock starts to melt.

Forgive my skepticism, but I think for the rod trick to even have a small effect it will need to be nearly bore size for more surface area to convect the heat away then change it out... seems like it would be as slow as just letting the barrel cool on its own. It could even prevent it from cooling by blocking any natural air flow.

Ive never actually timed it, but the fastest Ive ever been able to cool a barrel is with a barrel cooler blowing air plus a wet towel. Ive ran ice cubes over the barrel and that works really fast as well. Maybe 5 minutes. 10ish with just an air blower.

The rod idea seemed simple. Either the rod will get hot or it won't. It's probably all moot anyways. I think @RVTECH might be right, I just need to shoot and not worry about heat. If I can get 20 shot strings in every 20min, I will be happy.

Here's an idea of the use of a fan, tubing and a pistol or rifle case. I would imagine one could build this instead of spending $50.

Perhaps there is something better out there. I've never actually worried about it, being I bring multiples to shoot and let them cool on their own.

I dont know the science, I just know it wears a barrel out faster to shoot it hot. Every shot increases the throat length and causes firecracking, a hot chamber will increase that greater.
You can always just to the hand method, if its too hot to hold its too hot to shoot.

"You can always just to the hand method, if its too hot to hold its too hot to shoot."

That happens real quick in my 30-06 with sporter barrel. If there was ever a rifle to try shooting hot, this rifle is it. It's a $200 rifle, that doesn't shoot super great anyways. It won't be a big loss if I get some firecracking in throat.

Yes, overcomplicated. These ideas are mostly too much trouble for a recreational concept. I'm wondering about the need for masses of firepower during these sessions but never mind that. When I'm firing one of the M1 Rifles, I will fire off a couple of clips, then leave the bench, sit on my arse behind the line for about ten minutes reading a gun magazine. Then repeat.

This time of year, I go behind the range pavilion and pick blackberries for ten minutes, then return to my rifle. The trigger may get purple stained.

Whatever the material, you don't want to be dragging a rod in and out of the barrel excessively. That might hasten the end of your barrel more quickly than potential heat issues. I don't think they make bore guides for threaded rod. Aluminum, brass and copper may seem benign, but if they get dirt or grit on them, they can act as an agent for abrasive contaminants. Even wiping down the soft metals doesn't always remove all the grit. The more you fuss around, the more apt you are to introduce contaminants into the bore.

Your whole idea is to increase the amount of shooting time you have at the range. But all this fussing around burns up valuable time too.

Okay, having said the above, my vote is for an air blower.

Agreed, I will shoot it hot and not worry about it.

 

[Old John]

Will any of these cooling methods cause warpage of the barrel?

This is the first thing I thought of, especially if using a threaded rod.
