Saturday at the Movies — Barrel Coolers in Review
Summer Solstice is just four days away. That means shooters nationwide will soon be dealing with peak summer ambient temperatures. When it’s hot outside your barrels will heat up even faster during use — and that’s not good for barrel longevity or consistency during long strings of fire. If you want a barrel to have maximum useful life you need to keep it from getting very hot. That’s why you should have a barrel cooler. There are many variations, but the most popular models blow cooling air through the bore. This can reduce barrel temps significantly in a relatively short period of time.
For this Saturday Movies feature, we’ve found 7 videos that review commercial barrel coolers or show how to build your own cooler with a hose, small electric fan, and modified case. There are a variety of barrel coolers on the market currently. Three of the most popular coolers are the yellow BarrelCool, $39.99 at MidwayUSA, the red Magnetospeed RifleKuhl, $56.89 on Amazon ($59.99 MSRP), and the black/yellow Chamber Chiller BA PRO, $80.40 on Amazon.
Barrel Coolers — Why You Should Use Them
This video explains why it’s vitally important to keep your barrel cool, particularly when running a suppressor. The host, a long-range shooting instructor, explains: “The best way to extend your barrel life [is using] barrel coolers. We have learned through decades of shooting that keeping the barrel cool and cooling it as fast as possible between relays and strings of fire will return meaningful results in the longevity of your rifle barrel. If you shoot suppressed like we do, this brings the level of importance up to a whole new level. Keeping it cool will keep it running at its best longer than you ever thought possible.” The barrel cooler featured in this video is $65.00 on the Wolf Precision website.
Barrel Cooler Comparison Tests — Four Options
Barrel coolers are vital accessories that let you get more shots downrange with less time waiting. In this excellent, comparison test video LongRangeOnly’s Ryan Furman shows which barrel coolers will remove the most heat with the rate of air flow comparison. Ryan also covers some basic differences and attributes of each unit tested and tests the units with temp gauges. Units tested are the BarrelCool, Magnetospeed RifleKuhl, the blue-bodied Original Barrel Cooler (6:48 time-mark), and a large Coleman rechargeable Quick-Pump (8:12 time-mark). The latter two units provided the most airflow when fitted with an appropriate hose.
Build Your Own Barrel Cooler — New and Improved
Popular YouTube host F-Class John was one of the pioneers in building very affordable, yet very effective do-it-yourself barrel coolers. John initially used a hose fitted to a battery-powered black Rechargeable Mini Air Pump. John then tapered a hose to fit a cartridge case for a perfect fit in the chamber. The case-head was cut off to better fit the hose for maximum airflow.
F-Class John later created an upgraded barrel cooling system using smaller, more compact pumps. He would charge these with a high-capacity battery pack (see above) and a USB charging cord. As shown in the video above, this Gen 2 system proved to be very effective. John notes: “Make sure you watch how long you the pump runs and don’t let it overheat”. One of these USB-port Mini Air Pumps is currently available on Amazon for $29.98, and there are similar compact pumps for a bit less.
Chamber Chiller BA Pro vs. Magnetospeed RifleKuhl
This video compares two compact barrel coolers, the red Magnetospeed RifleKuhl, $56.89 on Amazon and the yellow Chamber Chiller BA PRO, $80.40 on Amazon. Hear the tester’s conclusions starting at the 2:40 time-mark. The tester reports that both the RifleKuhl and the Chamber Chiller fit well in the chambers. The two units cooled down barrels pretty much identically in the field. Measured with a Kestrel, the RifleKuhl had a 12 mph flow vs. 11 mph flow for the Chamber Chiller (3:03 time-mark). The deciding factors for the tester (1:32 time-mark) were the superior battery life of the Chamber Chiller (with an extra USB battery attached) and the quietness of the Chamber Chiller.
Riflekühl Barrel Cooler by MagnetoSpeed
The MagnetoSpeed Riflekühl barrel cooler is designed to get barrel temperatures down to intended operating levels quickly. The turbocharger-inspired impeller is engineered to produce great airflow in a small package. Powered by a single CR123A Lithium battery (included), ambient air is forced through the extendable nozzle down the bore of the rifle. This is pretty efficient and can typically cool a barrel in under 8 minutes. The Riflekühl doubles as a chamber flag and features an exclusive built-in air filter to prevent dust and dirt from being blown into your rifle.
DIY Barrel Cooler Made with Mattress Inflator and Hose
An average gun-owner can build a good barrel cooler relatively easily with low-cost components. In this GunMart.TV video from the UK, the host showcases a very effective barrel cooler he crafted with an electric mattress inflator and a hose. The unit has good flow and can cool a barrel in a couple of minutes (3:10 time-mark). These components can be purchased for under $30.00. The tester purchased his cooler fan for $14.99 on Amazon (3:40 time-mark).
