My vote would also be for the HW 30s, (as previously suggested by BBS member Andrew Richards), with the Rekord trigger, weighs 6lbs, produces 7ft/lbs and feels like a tuned gun out of the box has very little recoil and subsequently is extremely accurate. My son is 10 and when he could be bothered to shoot can load it himself and hits knock down targets at 30 yards.
I shoot it occasionaly and it always impresses. From memory you can special order them from your local HW dealer just takes two or three weeks at least it did last time I bought one.
