True that. My Husky 8x57 had a small piece of wood chip out of the tang area during the firing of a group. The shot during when the chip came out went 3" out of the mean group. After bedding, no misbehaving, accuracy-wise.~Muir
anyone have first hand experience of having a barrel bore scoped by a gunsmith

Well my miraculous discovery is not the issue!!
3 groups:
4 shots in a 8" diamond low
4 shots in a 3 shot 3" group low left and one flyer off to the high left by 6"!
3 shots in a 6" triangle mid left!
not even consistently crap!
So having purchased all the cleaning supplies on sale in the world I set about the barrel, frankly it wasnt that dirty!
I used KG1,2,3 and 4!
Doubt the clean can improve this morning's performance but suspect it is fubar'd.
gunsmith here I come.
gutted

Before you go buying a new barrel....... Try a different scope ..................... just in case even S&B's can go awry.....
The moving about point of Impact makes me wonder about the scope and possibly mounts...

mounts are rock solid, could be the scope I suppose, ........
irritating thing is that 18 months ago I personally shot a 3 shot 1" group with this rifle

crown is obscured by an integrated muzzle brake so difficult to tell, but in that it is doubtful that it could be damaged as it is protected by the brake.
was meant to go to the range today to see if the stripping, cleaning has improved it. couldnt make it so will have to wait a couple of weeks

I have been wondering how this rifle was getting on and I guess you've left it alone for a bit. If this were my rifle, i would do the following -and I do this for every gun giving me problems..
I'd doublecheck the screws and bedding (which you did)
I would switch optics.
If no improvement, I'd change out to a new lot of brass and prep it uniformly.
I'd then change seating depth or go to a heavier bullet.
Lastly, if all else failed, I'd cut that muzzle break off.

I have tried factory ammo, then using the once fired norma I have tried 130 and 150gn sp bullets.
had a chat with one of the members here about the scope. Its a S&B 4-12x50 which looks in good shape but you never know I suppose. I have another one I can use but it is my last call as it is not technically my rifle.
annoying thing is that I am pretty sure this rifle has has minimal use but some transit since I zeroed it and put three in a 2" bull with factory ammo in late 09.
I can only imagine it has had a knock as it has moved houses a couple of times.
scope is the next on the list if the clean and rebed hasnt helped!

Ahhh Muir,
This is the muzzle brake on the BSA:-
A big hole especially when you realise the rifle is a .243 win... No I have no idea why someone would wish for the MB on a .243.
That's the whole .243 Majestic
Sorry about the fuzzy photos I pinched Mothers camera as I was in a rush and simply cannot get on with it

In my ongoing pursuit of flogging a dead horse, I discovered something fairly fundamental about the way the action is seated into the stock.
I noticed the front screw was loose in the past and had hoped that the problem was resolved by tightening it up.
I have since noticed two things:
There is a hairline crack on the underside of the pistol grip/action area
and
The point of contact internally between stock and action is forward of the recoil lug and not the recoil lug itself, so when you tighten up the action screw at the front the barrel moves closer to the fore-end. slacken it and it goes further away!
it beds against the round area where the barrel meets the action:
refitting the bipod and standing it on the table I realise that the stock has the rigidity of a banana skin
I did this by holding the pistol grip and flexing my wrist with the same force I would use to accelerate on a moped!!:
now I have two options here as I see it (or three).
1) remove some of the material in front of the recoil lug void in the stock to allow the lug to bottom out (its not far off as I see it), this would bring the barrel closer to the stock and probably create more problems I think. thoughts?
2) build up the base of the recoil lug void so that when the front action screw is tightened the resistance is vertical through the wood between recoil lug and floorplate rather than whatever flex is in the wood/action on a triangle.
(or 3...pillar/bed the mounting areas and shave some of the inner fore-end out and layer some fibre glass in there to stop the twist that is so easy)
think I am going to ditch the bipod as well as it is the non swivel type that is bound to be imparting some different levels of twist on the stock from a non linear firing point.
could any or all of these be giving me the grouping issues?

made a decision
I am going to raise the profile of the recoil lug with a small aluminium spacer .75mm thick so it beds into the stock on tightening, has to be the best way. barrel will clear the stock by a few MM from the action forward.
ditching the bipod for a swivelling version I have to remove any twist in the stock.
range on sunday hopefully so will see what happens.
If I am not here monday you know why!!

RFD It to Norman Clark at Rugby Warwickshire.
He is a proper gunsmith and makes rifles for some of the UK's top Long Range shooters.
Norman has forgotten more than most so called gunsmiths will ever know.
They will do it for you at a very reasonable cost and give it you straight.
Ring up and ask for Norman, Mick or Dean.

thats 400+ miles one way trip for a £200 rifle.
If this doesnt improve it, I am going to make it into a cricket bat

Midway USA sells PTG crowning kits for about $80 US. They work well. Can you get them from Midway UK?? They are stupid simple to use and quite accurate.~Muir
EDIT: They do.
Under gunsmithing tools, cutters.
Look under PTG and choose the degree of crown. I like 11 degrees. All you need is the tool, a hacksaw, and a large tap wrench.

good to know.
Although I could fly to the US, walk to the midway HQ and return quicker than Midway UK deliver!!
think if I go down that route I would get it threaded for a moderator and done at the same time,
lets see if I can get it to shoot first!
Saw this many times with new rifles working at a reknown stalkers outfitters (those who know me know who that was!) Simple fact is that your rifle doesnt like the ammo your feeding it mate, try others and try lighter/heavier loads to see what it shoots best. Also the ammo you use (and if you've used the same for a long period of time) may have changed in terms of power calc and so - well you now you see the end result...
Also get a can of foam and soak the barrel in the stuff over 24hrs and then clean it - it'll be as clean as you can get it ....

Well so far it has been fed:
Norma 130gn SP
Norma 150gn SP
RWS 150gn SP
Federal 150gn SP
Federal 130gn SP
Home load
N165 charges from 47gn through to 60gn with Hornady 130gn SP at varying COL's
It has had a full carbon and copper anti fouling treatment before and after various loads/brands to eliminate further variance.
they only variable I have not looked at is the scope. (S&B 6-12x50, so I am fairly confident it is not falling apart) but if my latest stock/barrel clearance tweak does nothing then this the next thing to go.
To put this into perspective this exact rifle and scope put three in a 3" bull (factory norma 150gn) on a forestry commission rifle test done by me about 18 months ago when I last had this rifle in my possession.
It HAS to be something physical that has changed/is changing to impact the consistency of the shots.
Its not my rifle so short of sending it back "broken" I feel obligated to at least identify the cause before I give up...
sunday, last chance saloon...again!
