Actually you can beat the Mist. Just look at the chart. The 22-TD was better with subs and supers on the rifle. Plus you can put it on more than one host from 22LR to 5.7 machine-gun. The Mist was the loudest tested with supers, almost 5dB louder than the 22-TD. 5 dB is noticeable. You can't put the Mist on a pistol and it cost $150 more. I'd say its been beat.
It is loud with supers, but all I shoot are subs and can only hear bolt clink and shell hitting the ground with ten bullets all touching same hole @ 50 yds, I'd say that is absolute perfect performance.
