I've had 2 of the JW13A "Backpacker", 13" guns. I agree, fun guns...decently accurate, but I think if the OP Is still looking...my vote would be the Savage B series...or as a back-up, maybe a Mark II. The 13" barrelled guns are heavier than they should be for the size, which is fine for an adult. Having only owned one Savage 22 (other than our Rascal) I'd find it hard to imagine a 13" Norinco could out-shoot a Savage bolt gun...but I've been wrong before. lol
As a CZ/Anschutz fan mostly...I'm biting my lip a bit...BUT, will say that from an ease-of-use POV with good accuracy, you're hard-pressed to beat Savage for the price. I also find they load/chamber rounds with less effort than CZ/Anschutz, something everyone appreciates...especially youngsters.
