I like this exercise. I think I'm going to include this in my next range session. If I do I'll update with a picture.
In the meantime, I shot the following group at my last range session back in January. It was my 1st 5 shots of the day (and the 1st 5 shots in a long time...haven't been able to get to the range in quite some time, much longer than I'd care to admit).
I shot it using my 642 with 132gr PMC FMJ at ~10 yards, 2-handed, standing, no support. Carefully aimed each shot. Also, the gun is stock except for Spegel boot grips (i.e., no trigger work). It's the gun in my avatar.
The target is a BT-5 (my favorite, FYI) and the white rectangle is a 3"x5" adhesive mailing label.
Not great, but I don't think it's too bad, either. There's always room for improvement.
