Forget most of the so called advice one may see in this type of thread. It is the Dunning Kruger syndrome in operation.
Go to the basics.
Firstly the few JW15 barrels I have examined have been pretty rough although some shot quite well.
Try this.
Push a dry firmly fitting patch through the bore. If you feel tight and loose spots then that is an indication of a poor barrel or bad leading.
There is only one real cure for a bad barrel.
As for leading take the rifle out in the midday sun and position it so the muzzle end is brightly illuminated and you can view the bore preferably with magnification. If you can see any leading then that is part of your problem.
You might be able to fix the problem by cleaning the bore with JB paste which might also negate some of the roughness. One thing to be careful of is to have a physical barrier preventing the the jag passing out of the muzzle while making quite a few backward and forward strokes.
Generally perfection in the crown is of far less importance than gunsmiths claim. What is important is the quality of the rifling close to the crown.
Beyond that there there an array of issues that can affect rimfire accuracy, as distinct from centerfire accuracy, none of which respond to tinkering with bedding.

So your effectively saying that the ppl whom have given advice thus far in this thread - before you posted - are over estimating their abilities and knowledge, but you yourself are immune ?
And then you happen to give advice, that one might consider “advanced” - and advice that is prone to irreversible barrel damage if carelessly undertaken by someone inexperienced...hmmm interesting.

TassieTiger did I really say that or is the view expressed in your first statement akin to a snowflake seeing 'epistemological violence' in an opinion that challenges their preferred mindset, with a bit of ad hominem thrown in for good measure.
The path to solving any fault that is not immediately obvious is to systematically eliminate the most likely problem areas rather than offer one's favourite 'go to' solution.
The excessively poor grouping could have easily have been explained by a bad scope or mount, or shooting ability, but these factors were already addressed by the original poster.
Let's face reality, JW15 rifles are the cheapest 22's available and the few barrels that I have examined would have to be the roughest I have ever seen but that does not mean every one is no good so why not start in the most likely place first without affronting the original poster or subjecting him to any unnecessary costs or losses.
As for the second statement, since when has cleaning a barrel been considered "advanced"? Are you familiar at all with JB paste?
In my opinion 'careless inexperienced' people are capable of inflicting irreversible damage to just about any part of a firearm particularly when acting on the misguided belief they fully understand what they are doing.
To quote Harry Callahan (as portrayed by Clint Eastwood) "a man's got to know his limitations".
I just hope I know mine.

Yes mate - you did really say it. I couldn’t give a rats, call me what ever you want, snowflake, egotistical, I care not - I wasn’t one whom offered any meaningful advice re resolution for the fault, I don’t pretend to know as much as many here, so offered little on the subject, but plenty of other of good ppl did. Good ppl whom try and help and good ppl whom you decided to “straight shoot down”...adding insult with your Kruger comments...so quote your egotistical poems all you like. Glass remains glass and is easily seen through as well as broken.
Cleaning a barrel is not advanced - cleaning a barrel with a grinding paste to the extent of removing metal ? I know your not an idiot...so given the posters previous comments, it was clear he wasn’t experienced. Pretty big difference in running a few brushes in a .22 vs polishing out high/tight spots in the barrel...in fact I don’t care how in experienced or careless you might be - a few brushes is not going to hurt the barrel (or the warranty) no matter if you push them through with your dick, but imagine taking the rifle back to the shop and they find paste in the rifling ?
To further quote MR Callahan to you!, “it’s a question of methods. Everybody wants results, It’s just no one wants to do what they have to do to get them.”

I thought I'd report back on the outcome. After taking out the shims and shooting it again it didn't get better or worse. It would still group one or two then fling the rest all about. I followed Tassie Tigers advice and contacted the shop where I bought it and they asked me to bring it back so that they could test fire it on their indoor range. They came up with the same results so they changed the rings with no effect so they put a different scope on. Suddenly the rifle started to shoot straight. I took the option to buy a new scope and they shot it to check the grouping and zero. They only had a 20 metre range but the group was less that half an inch and on the bull. I shot it today and got the same result over 20 and 25 metres but the wind was very strong and over 50 they opened up so it wasn't worth continuing in the wind. Overall I'm pretty happy and am looking forward to having a shoot without the wind to see how it goes over 50mt. Thanks everyone for your suggestions.
