I went thru this a few months back.
My 308 really likes the 168 Match Kings, but I could not get confortable to use it for hunting.
Anyway, I found and loaded up some of the 165 Game Kings.. They ain't too shabby.
I don't know that I can always get that head shot.
I’ve shot several deer 175 bthp gmm, also shot them with m80 ball. I’m not gonna say it optium for the job but if you put a 30 cal bullet where it needs to go there’s not much walking around in the lower 48 that hold up to it.
