Any reason not to cut .223 back to 16.5”?

People also say animal behavior is favorable to a suppressor — but I have no experience there as mine are still in jail.

I'm a believer of this, I've culled mobs of deer, pigs and goats and when shooting a suppressed .223, the other animals tend to mill around confused as opposed to a boomer that has them hooning for the nearest cover.
