When I say "crack" it's probably just noticeably louder than the 770fps stuff which sounds more like a air rifle level of noise

What altitude do you shoot at? My mate in Twizel has a problem with most subsonic brands as the speed of sound is slower at altitude due to the less dense air, so many subsonics are not subsonic in the High Country. I can't recall which subsonic brand he finally decided was reliably subsonic for him, may have been CCI.

If the issue is "enough suppressor", have you tried shooting the suppressor wet? Detach, pour in water and empty it out, reattach, first couple shots are significantly quieter. I super-tuned a small steel suppressor with wire rolled mesh which would retain more wetness. Other option is to use KY gel, this basically will coat the inside of the suppressor with more water than it usually would hold without it squelching about. The water is SUPER effective at absorbing heat from the gases, remember back in science classes about something called "latent heat of vaporisation".

6 minute video, jump to 4 minutes for the bare bones and comparison.
