And you don't need pre-cut timber to build a house. Yeah you can use a black powder rifle, but why would you? It's about efficiency and simplicity. No, you don't need automatic weapons to hunt. Semi-auto, I'd definitely argue you kinda do.

If you are a good shot and know what you're doing then you just need one shot. USMC - one shot, one kill.

Cool we should test this out and have the secret service guarding democrats be limited to single shot weapons. See how well the pilot program works

I was referring to hunting type scenarios by civilians not protection details by the Secret Service or the military. I was not advancing an argument that the military should not have semi, or fully automatic weapons.
