I agree with the comment on "internet archers" I always hear about the tight groups but most of them equate to the 300/60x already mentioned. I practice out to 30-35 yards and that's what I limit my hunting shots to. I feel very confident to hit a 3-4 inch group to that MOST of the time but am 99% sure I can hit the kill zone on a deer, which is larger than that, every time.

I would say a 3 inch group is above average for hunting purposes.
