Interior wall penetration

[Candiru]

The question often comes up of what kind of self-defense arm is best for use within a dwelling when there's a high risk of collateral damage if the round ends up missing its target. Some compelling evidence suggested that high-velocity .223 rifle rounds might actually go through fewer walls than shotshells or handgun rounds, so I put together some wallboard sections and hit the range to find out for sure. The results were fairly surprising:

Thanks for sharing! I have tha 55gr TAP loaded up, but maybe its not the best option.

Looks like you put a good bit of work into that, it was very professional. Thanks for the info.

I have been told that some people build "stragatilicly placed" book shelves on walls to slow/stop bullets. It's not perfect but at least it is better than just dry wall and insulation. Just an idea for those people who happen to have 3,497 books lying around.

Thank you for sharing your work, and for your engaging write-up!

Fascinating! I'm shocked at the performance of the soft points. I'd expected they would have held together and sailed through all 3 walls. I may need to rethink my home defense load.

Good work. Might switch out my Hornady TAPs for some cheap soft point hunting round.
