I think it all depends on what you are trying to achieve!
Personally I can do a less than 10mm group at 25 yards standing using sticks. That goes down to a lot less when im shooting off a bench. I wouldn't know what my group is at 40 yards, but i regularly hit 25mm kills zones at HFT off sticks - so I guess it's less than 25mm! Lol
My aim is to hit targets at HFT, FT and occasionally Benchrest (now that requires some definite 5mm groups to be successful!)
However, if you want to hit tin cans at 10 yards then you dont need a Lothar Walther match barrelled gun, so it's horses for courses.
