John, some years ago, I took a very accomplished engineer shooting p. dogs with me, he was chief engineer on the B-1 Bomber project. We were shooting 600-1100 rounds of centerfire per day, EACH on the p. dog towns. Barrels were smoking to say the least in calibers from 223-243 AI. After we got home after 6000 rounds each of us fired, the Engineer said for me to come over to his house and he had come up with a barrel cooling system. Simple, he ran water right down the bore, then ran 4 patches down the bore on a tight punch type jag, dried the chamber, back to shooting. ONly took around 6 oz of water. When I questioned him on the water in the barrel, he said that until the bore gets to 800*, the water would never hurt the bore, and any tiny droplets of water left in the bore, would be vaporized by the gases that proceed the bullet down the bore. So, we have been using this video for 30 years on the finest Krieger, Hart, Lilja, Shilen SS barrels, and on Chrome moly factory barrels. Running the water down the barrel also had some additional benefits in that the tight patches remove a LOT of carbon. Folks are very, very reluctant to learn new things, we are all a product of what is popular. Best of luck to you!
I've seen some older video on this topic with the water and I totally agree that it can work but water is very unforgiving in F Class. A single drop of water on a round in the chamber can cause a 9 real easily, I've seen it happen many times when it's raining or wet out and people aren't coving their actions or taking care to dry their rounds. For p dogs I have no doubt it's a great solution and appreciate the feedback.
Hey John, because of the tight tube you're putting them in you should remove the air splitter in the front of the adapter on the white unit. This will result in significantly higher air speeds in this situation. Right now it's blowing a significant amount of air directly at the sides of the tube. Cheers!
I bought the one you recommended last time. Shipping to South Africa was more than the unit but well worth it. Still running great. The price went up since you made them popular 😂 Thanks for great tips!
Hello and I'm glad it helped even if shipping was high. II noticed the price went up quite a bit which is also why I searched for another option. But the size and running off a battery pack made this new one even better for me.
Yeah they're a good company too but I always get people who want to make something for themselves and in this case it fit my needs better. Lots of options is a good thing.
Great video bud . I bet if you took an insolated lunch box with some ice in it and drew your air from that it would cool even more . Would help keep motor and battery cooler too . But might sweat . Use a clear hose so you can watch for condensation .👍
It's an interesting proposition. But in my case(I don't target shoot, so cooling the barrel isn't important for my aplication) BUT I do hunt in very cold wheater, Point of impact will change from a very cold barrel in winter to summer sight in/load development. Puting a waterproof sock(The Blue cover game the idea) over the barrel and running freezing water over it might get a better very cold barrel first shot sight in, like your first shot at game 👍A styrofoam box with dry ice/Ice to place the barrel in might work to
I have a crazy crackpot idea that hooking up a mini shop vac would be better at cooling a barrel because it would suck out the hot air and pull cool air in. Still figuring out how to mount it. In the meantime, I am using a unit similar to your first one.
Won't work as well. The barrel diameter is too small for suction (pulling a vacuum into the pump). So you will end up with not a lot of airflow vs the pressurized method every one uses.
Been thinking about getting one live in New Mexico where it's really hot during the summer but I think the weight comparison was unfair you didn't weigh the blue one with its battery pack which is necessary to run it
I know people do it and I've done it when at the range fire forming (with a worn out barrel) but it's just not practical in any capacity at a match. Aside from that I don't want to shock my barrels like that either (there's debate on whether it actually hurts a barrel but I don't want to take any chances).
@@FClassJohn if your barrel is only getting up to 200 deg, it's well below any metallurgical change for the long term. I guess in the short term you run the risk of cooling it differently on one side which will put a very slight curve in it until the temperature equalized. Blowing air down the center would cool it symmetrically so that should maintain consistency
The "Original Barrel Cooler" will do 10 mph out the end of the barrel. Runs on batteries and lasts most of the day. Plus you can put in new batteries. What you REALLY need is a cordless Duster. Just put your hose on it and away you go.
John - off the subject here. I was wondering what optic you use for load development(at 100 yards). I’m curious as I currently use a golden eagle. I like a nice fine crosshair for load development . I’m in the market for another scope . What works for you. I really appreciate all your videos. Thanks in advance
To get down from 160 degrees to 115 I can do it with the cooler in less than ten minutes on average. If I let it sit it could honestly be 30-60 minutes.
Hey John! Love your videos. Just a random question, what size is your action? I'm guessing the heavy bullets might be a little much for the SA. Thanks!!
John, I like lithium-ion battery packs as well. Hopefully you are aware that there are FAA regulations regarding size and quantity. They can only be placed in carry-on luggage. Would hate to see an agent pull your batteries on the way to a match. UA-cam would not allow my comment with a link in it. If you google the following terms, the FAA regs will show up near the top of the list: Pack Safe - Batteries, lithium - Federal Aviation Administration
I dislike these things. They should not be allowed any where near the firing line. The high pitched whine is heard through everything. It’s quite annoying.

exactly what I was thinking

Great stuff John
Have you tried the Riflekuhl? I run mine in PRS matches between stages and it will use 1 CR123 battery on a very hot day and also acts as an ECI.
I also made a bore chiller from a R/C speed controller" which I had" and a laptop cooling fan.
Just looking at the video title, first I was like - I don't need it. Watched the video and completly oposite :D thanks
My pleasure. Glad it helps.
I think you mention Chamber Chiller on one of your videos, bought 2 for myself and brother-in-law - work great!
Yeah they're a good company too but I always get people who want to make something for themselves and in this case it fit my needs better. Lots of options is a good thing.

Dry ice
Cool. I wonder if there would be some flow increase if you cut the diffuser off the tip of the white nozzle.
Probably but I just haven’t done it yet.

Have you tried or seen others use an ice cold wet rag? Maybe the blower is better logistically and it works as a chamber flag

What are the realistic differences vs just letting it sit?
To get down from 160 degrees to 115 I can do it with the cooler in less than ten minutes on average. If I let it sit it could honestly be 30-60 minutes.
To bad that small pump isnt svailable anywhere else then maby Walmart USA.
Cant find them anywhere...
Got any other links for the plug in pump? They are unavailable.
Nicely done. TY If I use barrel temp strips..at what temp do you suggest using this cooler?
My goal is get my barrel down to about 115 or less before I shoot another string. I don’t love when it gets above 160.
Hey John! Love your videos. Just a random question, what size is your action? I'm guessing the heavy bullets might be a little much for the SA. Thanks!!
Thank you. I’m using a short action which is no big deal except you have to pull your bolt if you need to pull a round out.
Get one that sucks the heat out

Oh yeah, I'm definitely aware but appreciate the heads up and I've always made sure anything lithium goes in my backpack.
The smaller one you like is showing unavailable now with the link :(
John made them sell out.... I wonder how many they sold form this video. 🙂
What is the brand of the small $16 pump? I didn’t see any Amazon links.
They’re both in the first line of the video description.
Got it thanks
He said he “didn’t want a bigger unit”. ???? 🤔🤥
👍👍👍👍👍👀😎
Teach a man to fish, dont give him one
👍🏻
Unless the fish stinks.
No, it's not New and Improved. You cannot improve a new item. So it's either New or Improved, cannot be both. Ha.
I dislike these things. They should not be allowed any where near the firing line. The high pitched whine is heard through everything. It’s quite annoying.
With all due respect, that tone is Seriously Obnoxious
If you use one of these near the firing line, you should be uninvited from future matches. Incredibly annoying and rude.
