Andy Posted February 21, 2020 Report Share Posted February 21, 2020 I've searched for the past 30 minutes online trying to find someone that did decibel readings on suppressed subsonic .308 rounds with no luck. I know it all depends on bolt action vs semi, ammo used, suppressor etc etc. Just looking for an idea of average numbers, what I'll be running once my build and tax stamp are approved is a semi automatic 18" barrel, 200 grain subsonic round with an Omega 300. Thanks! Quote Link to comment Share on other sites More sharing options...

willbird Posted February 25, 2020 Report Share Posted February 25, 2020 The issue with DB readings is how they are taken. There is a specific instrument that should be used in a prescribed manner. And even on an indoor range with totally controlled conditions for the most part the data differs from day to day, probably small changes in humidity.

Andy Posted February 25, 2020 Author Report Share Posted February 25, 2020 Agreed willbird, I was just curious if anyone had actually used a decibel meter with suppressed .308 subsonic rounds (inside or outside). It appears no one else has that information yet either, I'm not needing this information for a dissertation or anything I just like looking at numbers (very curious how it compares to a sub 300 BO figures). My guess is that they should be about identical (same size round around: 200 grain, going the same speed). Quote Link to comment Share on other sites More sharing options...
