Even at FAC power levels a custom mod should be comparable to a HW running at 12fte
That's why I always start my measurements by shooting with stock HW silencer and then comparing the modded ones against that stock unit in the same closed environment. If you get past the dB peak thinking and start measuring with dB at certain frequency up to 20 kHz or even 40 kHz for game animals you'll start to see the difference. In addition plot in the human hearing frequency and how certain frequencies are muffled and you start to understand more. At the end there's really not that much difference at 12 fpe power level if you measure some 30M or 50M from the muzzle. Stick a HW and 90% of people will be happy at 12 fpe level. Go to 30 fpe or 60 fpe and things will be different though.
