You do not need a semi automatic to go pig hunting.

I've seen myself hunters in NZ take down wild boars with dogs to flush and knives to kill the boar.

Given the current premise that the second amendment is to defend against state tyranny then one thinks that it shouldn't be restricted to civilian weapons. It should be equivalent ones so that civilians have an equal footing vs the state.

Personally I think you should change the amendment to reflect modern society. Either make it regulated in the checked and licensed sense OR remove all regulation and explicitly make it an individuals right. It is an amendment, amend it as you will. Just make it make sense in a modern context, one where professional armies exist as the norm.
