/AKM/ - Guns, weapons and the art of war.

So I already have an ar15 and some 9mm pistols. So shtf/prepping is already covered. What I'm wondering is about getting an "Intimidation" setup. Which is basically as loud as possible and using really heavy bullets. The idea is that people would get freaked out and stay away from your area. I'm thinking an ar10 and a 10mm glock 20 would do this well. Maybe even throw in a 460 revolvers. I'm only interested in things a normal guy can buy in the US. So no super heavy weapons or explosives.

Is this a stupid plan? Feel like it's decent idea but also very retarded at the same time. What do you guys think?

I've never fired anything above 10mm so forgive me if I have a stupid idea of how larger calibers sound and function
