We have Silencerco and Dead air.  All do as advertised and I assume you know supersonic is still gonna be loud.  My best friend is a dealer so I get good advice.  Do a trust and with the electronic process now it's pretty quick on the turnaround.  Last one we did took about 3 weeks at the end of last year.  First ones 4 or 5 years ago took 6-8 months.  Individuals without a trust have been coming back next business day.  They are addictive but for deer depredation they are invaluable when paired with a thermal.  Buddy has other brands but generally when we've bought we've gone with the best available for what fit our needs.  If buying a 7.62 can now it likely wouldn't be a Silencerco but I'd have to ask him what that would be.
