Wouldn't that split case be caused by a chamber irregularity?

Whatever you do to it all your doing is polishing a turd
Well....my turd works just fine....[emoji3][emoji106][emoji41]Quote:

Didn't touch the bedding but obviously the crown was cleaned up during the threading. That thing shot like a demon, in fact better than his father's CZ. I can still remember my brother laughing like hell as I slaughtered stuff in their paddock out the kitchen window, much of it the wrong side of 70yds. That thing was extreme bang for buck.Quote:

Those split cases have been overlooked in this discussion, I have never seen that in any 22 before including two JW 15 and an EM. The split cases alone should be reason enough for a refund IMO
I've only used Winchester subsonics so far and only noticed 1 split case, will put some more rounds through it and see what happensQuote:

Not trying to be a jerk but.... would you be entitled to a refund when it's been chopped about? Different if you'd tested it first and found it shot like the proverbial shotgun and returned it. Not trying to shit stir at all. I just know that i wouldn't change anything until I'd tested it.
Good shitQuote:

Had one about 10 yrs ago.
Bought it one day, returned for a refund the next.
Foresight was bent at 45 deg angle. Not that it mattered as I wasn't going to use iron sights plus easily staightened.
Bolt was extremely difficult to close.
Wouldn't feed last round out of mag. Yeah, I could have gone and bought a CZ mag.
Safety wouldn't work not that I use them. Believe non operating safeties was common.
Crown not good. Cannot remember if bore centre.
Took out of stock and the bits that couldn't be seen when assembled had not been stained and the wood wasn't far off the colour of balsa wood.
Said I would be never buy Chinese firearm shite again. Since bought an EM332 :)
wife had a chinese sks, worked bloody well too. then komrade cindy took it off her and she got a 6.5grendell ruger american to replace it (2x the mag capacity and 4 times the range and 10X the accuracy.......but hey it makes people safer right...)
@Spoon Still a pain to buy something and it's not fit for purpose!
Funny how they build shit rifles but can make a not bad scope I think my sks would of been the best Chinese rifle I've owned and I think their bores are on center
Agreed. Tell your wife to look up Stangskyting on YouTube and she won't think much more about that SKS. What did she get for it btw?Quote:

They won't all do that though (whether 'prepped' or not), quality control is very loose. There are good ones and bad ones, sounds like you got a very good one.Quote:

Just take it back its spilting cases and its very inaccurate
This means not only is it unfit for use but unsafe aswell
My first ever rifle was an outdoor arms jw15, apart from its rough looks it shoots well and has been my go to for magpies for the past 10 years.
They are good project guns to have a real good tinker with, I would love to get a CZ but my jw just keeps performing.
Post up a pic when you're done muzza, I've got a JW here that needs a bit of trimming. On the to do list...
I had the misfortune of buy a dud jw15 couple years ago , didn't have norinco printed on receiver just jw15-s so guessing was a knock off , anyway the thing sprayed like a shotgun tryed all sorts of ammo and the best it could do was 5 - 6" at 50m.
so it sat in safe for a year till i got bored one day and thought bugger it not much to lose , out came the hacksaw file and drill , cut her down to 11" filed her up , crowned her with a drill bit , mounted a vx1 on top that i had lying around and hey presto tack driver now , shoot Winchester 40gr sub 1-1.5" groups at 80m, very handy pointy wee thing , barks a bit for a 22 being that short but fun , rough as guts but hey it works ! https://uploads.tapatalk-cdn.com/202...98c7472cbf.jpghttps://uploads.tapatalk-cdn.com/202...b9f7dee12a.jpg

Yes trimming barrel is easy. Pop it into vice, measure 16" from receiver (or the length you want), cut off with hacksaw, tidy end with grinder or file/wet and dry etc, then put appropriate size round head brass screw in drill, and work into bore end with grinding/lapping paste to create new crown. Then check by putting cotton bud in and out of bore to ensure no burrs, perfect crown. Does it work - about 20 done and all but one sub 1" at 50m, and most around 0.4-0.5" groups.
Wow they should make barrels for walther
I bought a plastic one as a spare/ hack work rifle. It was seriously rough to cycle bolt etc but the first 500 rds sorted that out. Cycles brilliantly with the right mag but picky with others. Shoots like a lazer. One ragged hole at 25m with pretty much anything. I tend to use Powerpoints or CCI subbies. You certainly get what you pay for and you pays your money and takes your chances. Mine works brilliantly.
They are not come from same factory. 'Norinco' is exporter, not factory.Quote:

I recall seeing a browning BLR in .243 in Buckleys sports shop in Timaru ABOUT 30 years ago...the bore was more off centre than that....surprised the heck out of me as have never seen centrefire off centre let alone as far off as the 243 was....
norinco is north china industries, they certainly do manufactureQuote:

The eccentrity of the bore is a fairly common thing in rifles and is of no real consequence in a field grade .22. Eccentricity of the muzzle and crown is a different thing altogether and needs to be corrected by shortening and recrowning correctly, recutting the suppressor thread accurately at the same time. Any competent gunsmith should be able to tune one up to give good performance. In my experience they are capable of 1-2 MOA which is pretty good in .22's.
the old toz rifle with the bell end muzzle, never seen one yet that was on center, sure shot good though
If you think you've seen bad ones, you should try being the poor sod who has to take them out of the box, remove them from the plastic bag containing the rifle and about half a KG of stinky cosmoline, strip it all down clean, then mount the POS scope that comes with them, before realising it's not fit for sale. When I was in the trade we would send an alarming proportion of JW-15's back to the importers before they even went on the shelf, off the top of my head, problems were included but not limited to:
Chamber not concentric to bore
Safety almost impossible to operate
Open sights canted so badly you couldn't line them up
Muzzle thread not concentric to the bore so the customer shatters the suppressor, and then the replacement suppressor with the first bullet through it
Sear being out of whack to the extent the thing wouldn't go off no matter how hard you pulled the trigger
Bolt being so rough that cycling the action was hard and inserting/removing the bolt pretty much required bracing the butt on the ground and 'mortaring' the thing
Off-centre bore
Seeming normal but then the customer finds you couldn't close the bolt on a live round
Seems to be a quality control issue rather than a quality issue per se; it's a good design and some of them are as good as the Brno/CZ they're copied off, most are rough but serviceable and the bolt wears smooth over time, and the rest are un-useable. I've also seen a few of the wooden stocked ones break through the pistol grip area, it's some kind of nasty Chinese soft wood (Chu wood I believe).
My JW15 got chopped to 14inchs.Just over legal minimum legth from barrel tip to butt tip.Just check on that.
I brought mine brand new when I was 16 as soon as I got my license.. Its never let me down..shot a few possums and deer with it over the years...Not the smoothest action, but still does the trick. Its a pity yours is that way!
Can't remember when I bought mine had it that long,second hand wood/blued, haven't done anything to it other than shot, has shot thousands of pest animals and the only problem I had was it sometimes left a shell in the chamber after firing. Put new extractors on it and it's fine. I find that the chamber gets a bit grubby after a lot of rounds so I use a nylon brush and scrub the chamber out From time to time. Can't fault mine only paid about a $100 for which was a bit back when I got but it has been a reliable straight shooter. Shot a 12mm and 14 mm group at 25 yds with Power Point HV and a 19 mm group with the cheaper Bushman ammo a few weeks back.
We've chopped, recrowned and polished action on about 20 JW15s and I really do rate them as worker 22s - as good as you'll get for the truck/quad. Almost all dropping under 0.5" at best at 50m after chop and recrown - even though bore often well off centre. Older ones often best, avoid GC ones and Polytech branded models - and from others comments it appears avoid latest GC Outdoor Arms models too.
The polishing and chop/recrown work takes about an hour or so - nothing too flash there. This brings out the Brno DNA and you have a deadly and efficient little hunter. Shot many thousands with mine.
