Norinco jw15a

Well firstly id like to thank WM for taking me to Belmont today to try out my new Norinco 22lr.
Ok, So after me and WM cleaned the gun last weekend he thought today would be a good day to see what it can do.
I bought a brick of federal standards and winchester bushman high velocity rounds.
Tried the federals first and after about 60 rounds the gun hadnt missed a beat every bullet fired and all ejected

Then i tried the Winchester and only fired about 12 rounds and out of those 3 were stuck in the chamber after firing.
had to get a small screw driver and pry them out carefully.
And now for accuracy. Well not sure if its the bullets or not but for a $199 22lr, i got what i paid for. Bullets were going everywhere lol.
Once we got the scope sighted in, the groups on average were about 3.5 inch at 50m.
Were thinking it could be the scope that came with the gun, its a sabre 4x40. not much to look at

Thanks again WM had a ball today :thumbsup:

Suggest you try a different scope and a few brands of ammo.

I had a very good time too

Have spent a lot of time and a bit of money on a couple of rifles and now they shoot very well.

As for Mongrel's rifle, the Norinco, I tried tweaking both take-down screws, one at a time, first one, then the other, both to no avail. All this, in case the bedding was the cause of poor groups but it became obvious that the problem was not just bad elevation. The rifle was missing the entire page

We were aiming at the SSAA 6 pack target and not only did we miss the aiming mark, sometimes I could not find a hole on paper

So, I think Oldbloke is right; a different scope is called for but time is running out for Mongrel. His trip to NSW is fast approaching and he doesn't get much time at his local range for experimenting. Stay tuned for the next exciting episode folks

Hey, Mongrel, fellow Norinco owner here, my one has brought me basically all the small game in the state of Tasmania and will take me into the SSAA rimfire comps next month. I'll let you in on a few things, for future reference:

Ok, so first thing's first, you are definitely going to need a good scope for it. One with low mounts too. The slant of that stock is a real pain and doesn't provide any kind of scope-height comb. I'm getting a new 3-9x40 variable to replace my 6x40, and it just clears the barrel and bolt when placed.

Secondly, free-float that barrel. Take the stock away from it, and use a Dremel or some other tool, with a sanding device of some kind, and deepen the channel. Keep placing the barreled action back into the stock and run a piece of paper through to check for tight spots. Bedding with shims is also a really good idea, I've got brass shims side-by-side of the screw-holes and supporting all key areas.

Thirdly, give all the moving parts a really good polish, say on a buffing wheel or from just a lot of steel wool and light grades of sandpaper. The bolt's camming action is very tight and takes a bit of effort when brand new, but after some TLC and light lubrication, it runs smooth. Hearing you've cleaned it is good, as when it comes in the box it has a lot of that mysterious Chinese packing oil. Clean all of it off every spot, degrease the entire thing and then spray it with water dispersant. Oh yeah, the trigger when it first arrives is horrendous. Take GunrackNZ's guide to improving it:
http://www.gunrack.co.nz/jw-15-trigger-improvement/

Fourthly, use any of the following ammo for best results, listed from most to least accurate:

Anything SK (Especially red-box match ammo))
Eley subsonic
Remington Subsonic
CCI Mini Mag
Winchester Super Speed
CCI Stingers
Winchester Powerpoint
CCI Quiet (Winchester Z's are junk and louder))

Happy shooting

You'll want to put a lot of rounds down the tube - without cleaning it - before it settles down. I wasn't particularly impressed with the accuracy of my Ruger American until I had the first 1000 rounds through it.
Don't buy bricks until you know what shoots well in it, just grab a box of everything you can find and try it out. I picked up some Eley Edge today which will make 24 types I've tried in the Ruger so far in my search for its favorite.
Most stuff it shoots ten into around 2" at 50 yards. Perhaps half a dozen types shoot worse than that. Two or maybe three types will shoot under 2" at 100 yards.
I'm confident I can get ten rounds of Eley Match into 1.5" at 100 yards with a little bit of concentration.

Sorry to ask the idiot question but did you double check the scope was mounted correctly and all screws were tight? Everyone has had this at some stage.

Also suggest you test free float the barrel with a washer a business card before you mess with the bedding. It may be OK as is.

Thanks guys lots of info here. That's what I love about this forum... Full of info and nice people to share it :thumbsup:

I will try the free floating first as that will be easiest for now. Then the scope as I have a Tasco 3x9x40 here.
Trigger adjustment seems to be in my capability, but as for polishing I will have to google it as I've nvr seen nor tried it.

Good idea.

Just an update on the Norinco... Went to yandina SSAA range today.
All i did to the gun was put a washer under the front screw of the action, which then i could slide a piece of paper ll the way down the barrel no restictions

And i also polished the bolt a bit with some Autosol(only to help the bolt slide better) which it did slightly.
Here is some picks of the targets at 25m and 50m after i tweaked the scope turrets.
