When you can stand on your hind legs, and get near the same size groups as you do from the bench, then you can be proud.
Most guys never shoot a group offhand. They have no idea how they can shoot in the field, since all their experience is off the bench.
Very true, about 20yrs ago my hunting buddy said exactly that,"why don't you get up off that bench and see how you do?"
I immediately realized I was practicing all wrong (for hunting that is)best I could do with three rounds was roughly 8", some were as bad as 12" and this out of a gun that will shoot 1.5 from the bench.
I built a set of shooting sticks and with those standing I can stay in the 1.5-3" range at 100, if you've never done it give it a try, it's a eye opener.
