Under 1" at 30 yards
30 yards is my gopher distance...
I use a denim-sack filled with dry field-peas as my rest across the hood of the truck.
After about 15 shots to get my scope where I wanted it the JW21 shot 10 shots in a group under an inch at 30 yards. The scope is an el-cheepo 3-7x tasco 3/4" rimfire scope (with rings) I had laying around taking up space in the safe. The scope seems to work OK, and as long as it continues to do that, I won't be dropping a hundred bucks for a new scope and rings.
The group size might improve if I wasn't using a truck as a rest, and it might improve if I swab the barrel. If the rest of the gun is any indication, it will be covered in that thick axle grease stuff that was smeared everywhere on the gun out-of-the-box.
1" group at 30 yards isn't super-great, but I've seen worse. Lets not condemn the gun until I can get it to a proper range on a proper rest, and expiriment with a much better scope.
When I'm walking around the field plinkin' at gophers, there's no way in h_ I can hand hold a 1" group at 30 yards.
I've carved myself up a walking stick with a grip rest at shooting height, that improves my hold a whole bunch. But the rest-stick can be a three-handed ngihtmare when walking. At least a lever-gun is easier handling than a bolt.
The JW 21 is weird, in that when you click the lever out of the home position, the trigger can still be pulled to drop the hammer. I'm not sure if the cartridge would fire if the lever wasn't fully home and thus the bolt not fully home, but I'm not going to try. Its just that with my Browning BLR 308, you can click the lever out of the home position for another level of safety - on the browning, if the lever isn't all the way home the trigger will NOT drop the hammer. Not so on the Norinco.
All the best, I'll post more when I shoot more.
