For this reason I would personally choose the AK.

I know we like to get all hung up on accuracy, and splitting hairs. However, that is not the intended purpose of this style of rifle OR the specific round. Energy falls off pretty fast.

That being the case, quick reloads and more importantly, already prepared reloads, and not having to worry about strippers would be the deciding factor for me.

Assault rifle and good bolt action will do all that you need.
