Not an issue shooting a firearm. But, I have a G. Shep, and kids. I do not want chaos in such a situation. 

And no, I have my bow rigged with a fishing rig (I only hunt carp anymore). 
It will NOT be punching through multiple walls. Unless the target is about a meter away, this arrow will embed itself into the hit object, be it a wall, or a person. And it will penetrate most vests easily. 

OTOH, a broad-head or target with 100+ lbs behind it can go through 1/2", but it not go through a second one.
