Took a pair of JW14's out a few weekends ago. Both of them seemed to prefer Remington Yellow Jacket ammo, groups at 25 yards were less than an inch with optics and just over an inch with iron sights. The iron sights suck, the front blade is too wide to allow light past it when it is lined up with the rear. To hit point of aim at 25 yards I had the rear sight set for about 65 meters. Trigger is quite nice for a cheap rifle. I ran 250 rounds through my iron sighted model before I managed to induce a jam, a FTF. The magazines are METAL and quite durable, they will cut your thumb occasionally when you load them. Now, for the price they are an ok rifle. A few years ago when one could pick up a Savage or a Remmy semi-auto for 149 this Norinco would have been a waste of money. If you are a rimfire collector it is a nice rifle to have in the safe and occasionally shoot. If it is going to be your go to rifle I would recommend a 10/22, 597, 64G or a Marlin. The stock is quite fat on the JW14 and not very comfortable, the weight of the rifle is also getting up there. The iron sights are crap and it is a pain in the ass to reassemble after cleaning.
One of the few upsides to the rifle is that it uses Marlin 925 ect. mags. You can get them in 7 round, 10 round and 15 round flavours. There is a 25 round banana mag that Marlin made back in the day but they are quite rare and fragile (poor quality plastic magazine).
