    Isn't .300 Blackout the same as .300 Whisper?

    No. One is harder to see, and the other is way more quiet.

    He said 5/8" groups. Pretty nice. How are the long range ballistics of .300 blackout? I imagine it has huge drop, but does it still make tight groups?

    Yes he did say 5/8 groups but that was Kevin the gunsmith shooting it
    not the op.
    It will shoot the same as a 300 Whisper and will drop like a rock past 100
    yrds like any subsonic ammo does.
    Here is somes balistics for the 300 whisper/300 Blackout using 220 and 240 grn bullets, as you can see the bullet drop for the match bullets isnt much diference than the Round nose and 270 grn cast lead is close to the same.
