    Subsonic rifle ammunition is stupid and pointless for civilian and LEO use. Full stop. The only point to subsonic suppressed rifle rounds is for sentry elimination on covert military operations. If you're a civilian or a cop, repeat after me; "I AM NOT A SPECOPS WARFIGHTER. I WILL NOT DO BALLISTICALLY STUPID S*** WITH MY RIFLE."

    Why the hell would I want to turn my rifle into a gigantic pistol? I have a handgun for that. Jesus Christ people...

      @M Bear Suppressed hog hunting within 150 yards at night in Texas, that’s why. It works great for that purpose.

    Is this round good for small deer?
    How quiet is it unsuppressed?
    If it is only as good as a 45ACP why not just go back to the De Lisle Carbine (which has a large COOL factor) Or a pistol caliber bolt action rifle (Ruger range rifle would be great)

      @Mike In subsonic form it is unacceptable for small deer, in supersonic form it is marginal.
