This morning we were out at the range in the 26 degree weather, freezing our butts off. You non-Texans may laugh at that; but, trust me when I say it was truly cold – especially with a light breeze thrown in.
Regardless, we did set up the sound meter and spent time testing some of our more common .308 direct-thread suppressors.
We only shot about 20 rounds, but it was obvious that the sound meter results in cold weather were definitely different than we’re used to seeing on warmer days. In fact, they were off between 5 to 10 decibels from what we typically see; although, the suppressors still lined up the same relative to each other.
The most important take-away here is that it isn’t overly useful to compare suppression numbers from testing that happened on different days, or in different conditions. This also applies to comparing suppression results from different manufacturers, since they all have slight variations in environment, equipment, ammunition, and even testing methods.
As a general rule, it makes the most sense to only compare numbers when the suppressors were actually shot side-by-side in the same environment. That’s a big part of the reason why we try to shoot all the comparable models side-by-side on different platforms – just so we know how they really stack up.
We have been pretty crazy around here lately; but, stay tuned as we make more of an effort to publish comparison results and videos for all of our suppressors!
