My deer gun...a Rem 760 in .270....shoots about 2" groups at 100 yards, and that' s wonderful by me.

I have a 223 that shoots nearly hole-in-hole groups at 100yds (if I do my job)

It takes a good combo of bullet/shooter/conditions to get great groups. For hunting, groups aren' t as important as they are if you' re punching paper. Just make sure you can put them in the kill zone each time, and be happy!
