I don't always agree with with Formidosilus, but am 100% in agreement with him on this stuff.
When you hear someone talk about wanting to use 300 Blk subsonics for reduced penetration in a home, you can be sure that person does not have any experience with this stuff. There is a very limited selection of bullets that actually perform correctly in subsonic 30 cal rifle loads of any headstamp, and if you use anything else, penetration through meat and home building materials is astronomically higher than a good 223 or 300 supersonic load.
I don't know why people have such a hard time wrapping their head around supersonic 300 loads. It's just a 7.62x39 in an AR15, with better bullets and without the feed issues. No more, no less. It's not a 30 carbine, or a 30/30, just a better development on a common soviet cartridge that's proven to work acceptably well all over the world.
