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’s superior cooling performance has made it a high-demand product, and it will be on store shelves soon.
