I often hear about everybody's best groups. Some are downright amazing as I've seen the targets posted.
But how good are you at 100 yards, when using nothing but your gun and the bench. You know, just your own body for support....crook of the elbow...whatever style you find that off the bench, with no other forms of support or rest, gives you the best accuracy...
And what is your best group, from what rifle, when going "naked" at the bench???
