Here you go guys. Discreet Ballistics 190 subs from a 20” and 24" 308 using a B&K 2209 to get shooters ear numbers. Sorry but it was a bit windy for accuracy testing as you can hear. I like unedited iPhone videos for you guy. I tried to place things so you can clearly see the meter reading yourself.
