Yes, I agree. 5 acres is kinda of like a giant yard.I would want too shoot so much it would sound like a gun range was in operation and I am sure with the neighbors so close they would quickly hate me unless they all had shooting ranges in their back yard, then it would be perfect.
I need more land and way far away from other people.
10 acres seems too small and 20 is just getting started depending on how far from other houses it is.
That is my take on it. I could be off base though
