What sort of accuracy are you chasing? What does it shoot now?
When you clean it, are you removing much copper ?
What caliber is it? I presume it is some sort of 6.5mm not a light artillery piece?

What groups are you getting, what are you expecting? How are you setting up your bench? Etc etc - all answers will help diagnose .,,.but - Not that long ago, I bought a steyr pro hunter 30-06. Months and loads later - I gave up and returned the riflevto the manufacturers- I was 100% out of ideas.
The manufacturers confirmed a dud ...it does happen.

Sounds like mine at 100 yards will all over the place no consistency at all. Have tried every think in the book got me frazzled as are supposed to be a very accuate gun. Cost of a new barrell in Australia about $1200 to be put on gun cost 500 second hand

You have a 6.5mm Creedmoor, I am a bit slow catching on. Get yourself some known accurate bullets like a Sierra Match King. Get them going around 3,000 fps and see how they group. Have you tried bedding the action?

I feel your pain.6.5 Creedmoor are supposed to be that latest 1000 metre rifle on a budget.You mentioned you use solvent for copper.It wont touch it you need sweets or something similar I bought some 10 years ago and still have some and put it on a patch and push it through a few times then let it sit for 5 minutes brush a few times then run clean dry patches until the blue stops Then do it all again until I get clean patches first time you should be good for a while depending on how often you shoot.You say you got it second hand so you have no idea what its been through

If you reload go for the lower end of speed I have found that doing around 2800fps to be good for accuracy.My 7mm rem mag spits 168gn Matchkings around 2800 and it is super accurate.If everything fails recrown it.If that fails I will buy it of you as I have a target rifle but nothing in 6.5

I would personally Try some 95’s and some 120’s before completely writing it off and using it has a star pocket driver - you’ve tried 140’s whichbis the top end, try lighter and faster...
This is exactly what transpired with my steyr 06 - it wouldn’t group 180’s or 200’s but did okay with 150’s and 125’s.

You haven’t mentioned group sizes?

Jarrahdale ssaa. Yes I've tried 95. 123 they shoot worse. It's got to be something but I can't work it out. As 6.5 is usually very accurate round. Groups there is none as I have said like shot gun pattern

I know the Jarrahdale area can non members shoot there.I do field rifle.I believe that it is now called that as it was getting confusing with all the F-classes going on.I was doing F-class optical with the 7mm Remington Sendero..I have been to Armadale /Byford up Pickering brook way

Have you measured the velocity of your loads and compared them to Hornady Factory Loads. Not sure if it's still the case but I did read that Hornady was using 41.7gr of AR2209 with their 140gr Bullets. I also have read that in the beginning they had trouble with blown primers as their loads were a bit too hot. Also read that some that liked the hot loads switched to Lapua Small Primer Cases so they could load hot without problems. I wonder if you have tried increasing your powder weights a tad.

I don't have a 6.5 Creedmoor so I can't give you specific help with that calibre. Had a neighbour drop in here with his Son about a week or so ago with his brand new Tikka in 6.5 Creedmoor to sight it in using my bench and gear. Factory loads (didn't take notice of the brand) and it was shooting around 1/2 MOA doing well under 1" at 200 yards.

I do have a 6.5x47 Lapua, actually 3 of them. I know that AR2209 does not perform well with a 140gr Bullet compared to using 130gr Bullets with AR2208 (37.6gr for a velocity of about 2,900fps) but it is a smaller case and I do know that accuracy / velocity wise it's very close to the Creedmoor. Since all three are used for target all bullets are jammed like 0.020" but with little neck tension it's more like called soft seating as the bullet is pushed back into the case on bolt closure. I have tested a lot with seating depth even back to a 0.120" jump but none were very accurate at all no matter which type of bullet but mostly VLD's.

I wouldn't give up just yet. I'd try a few more ideas like increasing powder load, jam to jump bullets and even changing primers. If possible I'd try changing the neck tension as well.

Hope you find some better results. I thought of getting a 6.5mm Creedmoor purely for the reason of entering Factory Class Target and knowing it is supposed to be a very accurate calibre.

All my testing is done on a very sturdy bench with a front joystick rest and quality benchrest rear bag.

Seems you guys are having some other discussion so I guess it's best leave you with the topic at hand to sort out yourselves....

Got a predator in .223 first 2 times to the range and I was sure I had a factory dud, would group at about 5 inches at 100 yards, no pattern to them at all, all sorts of ammo would do the same thing, checked rings, bases, took action out of stock and checked it was free floating, nothing I did made a difference. Last idea I had was to put it in a fde ranch stock I had laying around that I brought as a spare for my standard .243 American. Next trip to the range it put 5 s**ts into 3/4 inch at 100, dunno what the go was but obviously stock related. But as you’ve already said, you’ve tried that. I was a little hesitant buying the predator in the first place because I’d read more than a few bad reviews about them spraying shots all over the place...
