Chamber Chiller Rifle Barrel Cooler Prototypes

Order Chamber Chiller Prototypes That Fit Your Rifle

By Olin Coles

When metal heats, the molecules excite and cause expansion. When metal becomes overheated, barrel harmonics also change, vibration increases, and shots begin to vertically string. A hot barrel also contributes to pressure failures, and increased throat erosion. You want a cool barrel so that each shot is consistent, and wear is minimized. This is why I’ve created the “Chamber Chiller” rifle barrel cooling fan.

After testing homemade and commercially-available barrel cooling devices, I discovered several key areas that could be improved for better performance and functionality. As a result, I designed and developed my own Chamber Chiller rifle barrel cooling fan devices. These are functional products, but since each device is 3D printed and hand assembled with off-the-shelf parts it’s appropriate to label them as working prototypes.

The idea behind Chamber Chiller is simple: cool the chamber where heat often sinks into the loaded cartridge causing higher pressure, and deliver cool air down even the longest rifle barrel using a high-output fan. Impressive air volume forced past the barrel tenon at a high static pressure means much less time is needed for cooling-down, which also equals quicker recovery to optimal operating temperatures.

Chamber Chiller comes in two configurations: the 50-series utilizes four AAA batteries and a high-output 50 mm fan for most all common rifles cartridges, while the 60-series utilizes four AA batteries and a 60 mm fan for extreme barrel cooling in big bore and high-power rifles. Each Chamber Chiller prototype arrives with a satin black finish, allowing you to paint the unit any color you wish or begin using it as-is.

OMEGA features an 8mm ID nozzle that fits .223 up to 6.5 chambers, and BETA features a larger 10.4mm ID nozzle that fits 6mm up to .338LM cartridges. You can see Chamber Chiller in this video comparing my prototype coolers to the competition: https://youtu.be/Dyem0dfJOhU

Performance Comparison Results:
Other brand: 6.3 grains max downforce out of a 6mm ID opening.
OMEGA-50: 21.8 grains of downforce out of a 8mm ID opening.
BETA-60: 24.4 grains of downforce out of a 10.4mm ID opening.

I’ve already built and tested several Chamber Chiller barrel cooling fan prototypes, but I know that overheating is a problem for plenty of shooters. A cooled barrel gives shooters and edge over their competition.
