I concur with Locutus. I would suggest Hornady 55gr. Tap.
This round would serve the purpose for what you want.
The issue of penetration regarding walls. There is no weapon that would be fired in a home that will not penetrate walls unless maybe a BB Gun! So the most important thing is to select the best round and this one fits the bill for the AR or 223 rifle. A lot of people do not realize that a 9mm bullet from a pistol can penetrate 3 to 4 complete walls. So the Tap will be less. Main thing is to know #1. The field of fire compared to where the perpetrator is positioned and #2. Relationship with loved ones located in other areas of the house. And also to be "Absolutely Positive of the target!!!! (Especialy at night and coming out of a sleep!)
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
