For whatever reason, I've never seen one before. But at the range today a fellow shooter was using one.
Do they actually work?
Going to get into reloading soon and wonder if one would help during load development sessions.

Is a water jacket option available?
Not familiar with that either.Quote:

It's kind of a joke, but I wouldn't be too surprised if someone is making Maxim gun style water jackets for AR's.Quote:

On a more serious note, I remember barrel cooling fans being discussed on a podcast a year or two ago (maybe Frank Galli's Everyday Sniper?) and the consensus was most of them are a gimmick.

C'mon man, you don't need any of those fancy gimmicks!
Just load up on coffee before/during your range session and you will have no problem cooling off that barrel whenever you need to.
I've never used a barrel cooler. While they probably aid a little in cooling, I just run a heavy barrel, slow down between shots, and shoot calibers that use less powder.
What will they think of next? How about one that cleans and cools?

I’ve used one doing precision work. It works. I can’t remember the name of mine, but it’s yellow, about 4” square and about 1/2” thick. Has a rigid tube you put in the chamber. It moves just enough air to allow for more rapid cooling between strings. I think I have it with me in my bag. I’ll dig it out and take a pic.

Apparently those bullets did not like the heat of the barrel from not cooling down enough on the hot day with high round count stages. Most people don't need them, I just remember being reminded to leave my bolt open to allow heat to escape while I was loading up another magazine.
Here's a thread on the Hornady's blowing up which includes the video below https://www.snipershide.com/shooting...ng-up.7013159/

Also, I'm not insisting a barrel cooler would have alleviated the exploding bullet issue, but Dan did not have any more explode during that match after borrowing the cooler.
Video and post from Frank Galli:
"Slow-motion of a 147gr blowing up, every first-round from a cool rifle this happened, but the rest were sub 1/2 MOA at distance and at 100... the shooter was a cool customer, we just called them a foul ball, but this is getting crazy the number of 147s not making it to the target."

Maybe a production problem??
I think it is a design issue.Quote:

Here ya go. Like I said, I use it doing precision work especially when sighting in. I’ll shoot a string, toss it in the bore, do my dope book and paperwork, continue shooting. You can definitely tell a temp difference of the air exiting the bore after a few minutes of running it.
Probably come with a complimentary stuffed Jackalope.😁Quote:

Ok, passing on second hand information which I don’t like doing. It’s my understanding that while they do aide in cooling, not much more than normal radiation. None of my .mil peeps use them. When I asked about them, I was told they just open the bolt and set the rifle on the butt so the heat easily escapes the raised bore.
I believe the issue with 147's blowing up was limited to one batch.
I’ve personally dealt with 147 eldm factory loads blowing up. These were LE marked boxes and SKUs. They were generally less than 0.5 moa in my and my partners rifles. But every once in a while, one would just “disappear” mid air. As in- fire 3 and stack them on a steel at say 500, then #4 would just never make it to the target. #5 would be right back with the rest.
We then changed to the 140 eldm and have had zero issues.
I'd consider using one to help get a suppressor cool enough for storage after getting it hot on the range. Otherwise, nah.
Yes, that's amplified by higher velocities (~3,000 FPS) and heat.Quote:

I use this one.Quote:

Most sporting rifles don't lend themselves to mirage shields, so you have to let their barrels cool. I hate sitting around waiting for that.Quote:

I got to the range and hung targets at 25, 100, and 200 yards. The 7-08 will put first three shots nearly touching but then groups start to walk, so I'd shoot three, stick the cooler in it, and shoot two or three groups with the 308. Then I'd stick the cooler in the 308 and shoot another group in the 7-08. Arrival at the range to departure was about 45 minutes, including hanging/retrieving targets.
Barrels take a while to cool in warm weather, so I definitely use it for working up loads in the summer. Double-based powders like N560 burn surprisingly hotter than single-based powders, so if I use them in charges over about 58 grains, then I use the cooler even in the winter.
I see only two downsides to the Riflekuhl: it makes a high-pitched whine that attracts a lot of attention and inane conversation, and it eats batteries like a fat kid eats cake.
