@Alaska LukeWipartimer my brother has shot both well if I recall. But I'm warming up to the 308 idea a bit. It can use a suppressor which is nice. No muzzle blast to distract me while I watch as back him up. Of course I want it to be his kill so I'm hoping he downs it without help.
Go with the 358.
A lot more punch at close range and a BIGGER hole to start with.
