I'm in the process of building an AR pistol in 300 Blackout for home defense use. It will eventually be SBR'd and suppressed once the trust is set up and funds accumulate a bit. Until it's suppressed, what ammo would you guys run for home defense? The basic choices are a heavier subsonic bullet that gives handgun levels of muzzle energy or a lighter supersonic load that provides low end rifle levels of muzzle energy. I've run the pistol with both and it cycles both well without a suppressor, so I don't think reliability will play a role.
From what I gather, the advantage of the subsonic round for home defense is that it's going to cause less hearing damage than the supersonic loads, have less muzzle flash and be less likely to over penetrate. The advantage to the lighter, supersonic rounds is over double the muzzle energy when compared to the heavier bullet. Right now, I'm thinking that the heavier round makes more sense in a home defense role, but am I missing something in my logic?
What say the INGO brain trust?
