Suppressors Suppressor temps at high rates of fire

[TimK]

I bought a Fluke infrared thermometers for another purpose a while back. I took it to our local tactical rifle match and used it to measure can temps at the end of a stage. I checked 4 or 5 cans. Guys were firing 50-55 rounds in 2-3 minutes. Can temps were in the 600°F - 700°F range. The winner for the day came it at 715°. IIRC, TB recommends a max of 800°F. Every one I checked had a can cover on it. The covers were starting to smoke on the really hot ones.

I'd been wondering for years if I was overcooking my cans at this match. I'm pleased to know I'm under the threshold.

I was interested to see a huge temperature gradient from front to back on one of the cans I checked. The rifle end was 300° cooler than the exit end. Kinda counterintuitive, but the Fluke doesn't lie.

50-55 rounds in 3 minutes seems like ALOT for a match. Surely not on a bolt gun?

Someone (TBAC i think) did a video and used Templaq, 2 30 round mags in under 1 min pushed the temp past 800. I will see if I can find the video.

No, a "Tactical Rifle" match. Basically, the rifle portion of 3-gun. Every one I checked was an AR shooting 5.56, IIRC.

Ir temp guns are only so accurate as Temps increase.








Should be enough info

Yep, that is video i was talking about.
I believe (could be wrong) stainless steel cans, and inconel can handle more heat, their down fall is weight.
