Korean Redneck ,
What do you think of the 168 or 175 Sierra matchkings as hunting rounds?
Sorry, when I hear 308 I always assume punching paper and hitting steel. Never tried as my hunting experience is more limited. However, I don't think I'd try it with any bthp.
But then again I have a different approach to hunting ammo.
Since I'm usually fairly comfortable with my 308 and if i were to hunt with, then I'd actually start with winchester silver box and/or remington core-lot. You never know if one of the cheaper ones end up shooting well enough (let's say sub -moa at a range). It's rare but you might get really lucky and find one that your rifle likes.
If not, I'd look more at the bullet than the ammo manufacturer. In my experience, and I'll through Chad/Dallas Custom in the following mix, I wouldn't hesitate one bit to try a smaller manufacturer if they produce it with bullet you're looking for. I can be douche about hunting ethics, meaning I'd rather error on conservative side and give bullet selection some thought is important in doing so.
For example: if this were for a larger game animal (much bigger than white-tail), then I'd start looking for something like a Hornady 180 eld-x or 180gr Nosler partition or a barnes TSX bullet. Something on the heavier side and good, known bullet.
If it were more medium game, then I personally just like 150 or 165gr sierra gamekings.
Btw, my 308 is beast in terms of size and I have a 30-06 so I don't hunt with my 308, yet.
