Two things:
First you left Democrats off your list
Second, and this is just my opinion, 300 blackout is overkill for the species you listed.
Supersonics, yes, maybe... although I tend to be a fan of using a sufficient caliber to make sure that what gets shot stays shot.
Subsonics are a different matter. These are roughly ballistically equivalent to a .45acp, except you have a spitzer bullet. Only effective out to 150 yards, if that. But with the undergrowth here, it's rare to get a shot that's half that distance.
