Yes all testing done with m193. The stuff everyone buys for cheap. I should also say that apartment style life is another concern. Not just those who own a house. Huge liability. And our test with #4 shot was the best of the bunch. I agree with you that there are probably rounds like you mention that perform better. But your average joe probably won't be using them due to cost and availability. If you use an AR as your only or primary gun for SD, you have to understand. Being a handgunner mostly for my entire life I would not attempt to shot a fmj 9mm in my house for SD. But I see it a lot, someone gets their CCw and buy a box of Winchester white box. AR velocities are just to high not to expect some major penetration.
