i have a super short magnum .243; not hardly a box of shells shot from it. I could not site it in with 7 shots; took it to gun smith; kept it for 5 days and can not get it even close at 100 yards. Every shot is off the mark. Any ideas-as this is still a new gun-even though i bought it 2 years ago.
winchester model 70 accuracy problem

There are a multitude of things that could be wrong. You'll have to help the members narrow it down for you. Welcome to the board, BTW, play nice and join in is the main requirement of the board.
First - I anticipate you have a scope on the rifle. At what range are you attempting to sight-in at? You would be well served to start for dead center grouping at 25 yards if you haven't done so already.
2nd - Have you checked the bedding screws for proper torque? Loose screws will jillflirt any grouping efforts.
3rd - Ditto the above for scope mount/ring screws.
4th - What are you using for a rest? Sand bags or a commercial rifle rest are best off a bench. Motor hoods, rocks, tree limbs, etc. should only be used if nothing else is available. These should be padded with some sort of material.
5th and final for this lesson - If using supports, get the front rest as far back toward the receiver as possible and cradle the buttstock into the shoulder. Have enough scope relief to see the entire scope picture, but don't stock crawl to put your eye/nose at hazard. To start with, try cranking the scope down to the lowest power setting and still see your target well.
Did your gunsmith check the barrel channel to assure the barrel wasn't having tight spots with the stock?

I'm confused... Are you saying that you don't have enough windage or elevation adjustment to get it "on the mark"?
If that's the case perhaps the scope base mount holes are drilled off center or maybe there's something wrong with the rings or bases themselves?
Are you sure you have the right rings and bases for you rifle?
Any extra info would help.

.243 wssm
yes--the gunsmith was at the range I use....He checked everything-also had another expert double check everything---and they feel the barrel is possibly defective from the factory..Was wondering if anyone has ever heard of this with this model; and if you might agree with their assesment? thks

It is possible but like the guys have said, when you hear hoofbeats, think horses, not zebras and go for the usual culprits first. Once you KNOW those are solid, then think zebras ie barrel screw up from the factory.

Ruling out the possibilities in kdub's post, it is always possible that you got a gun with a bad barrel, or something worse. However, have you or your gunsmiths inspected the barrel crown for burrs?
Have you gotten any grouping at all on paper targets - wide grouping - or are you just off-paper with no idea?

Try some different ammo. If your present ammo is 100 grain bullets get something in the 85-87 grain range. If you are already shooting the lighter bullet, get a heavier one. Some guns just don't like certain bullets/loads. Kind of hard to pass judgement on the gun if you have only tried one kind of ammo.
The WSSM's are generally very accurate, but can be finicky about loads-the factory ammo leaves alot to be desired as far as tru accuracy potential. Generally accuracy is best with the lighter bullets. Have you tried tightening the action screws? I have also had two different WSSM's loosen the scope mounts (base plates) after a few shots, somrthing I rarely have ever had a problem with in other guns. Maybe is is just a coinsidence mabe not. If the shots are all over the place I would suspect mounts, scope or loose action. If the barrel is that bad a good gunsmith should be able to find the defect. I suspect its a simple fix or load developement issue.

Phoneman, swap the scope out if you can.
Over the course of time, I've had a couple scopes kick the bucket on me. One, well known for quality and durability, would only respond to vertical adjustments, and I didn't figure it out until I moved up to 25yds.
Another scope, not a junker, simply floated POI, an internal problem of some sort, and it took a couple boxes to figure that out.
Both were on rifles that couldn't be bore sighted, making it harder to find.

I think they're right.
Me and buddy of mine both bought Model 70 223 WSSMs at the same time. I didn't have any problems with mine, but he had all sorts of problems with his. He tried 2 or 3 different scopes thinking that was the problem...turned out the barrel was defective. I've heard of a few people having problems with this.
I was fairly happy with my super-short minus the cost of ammo, so I got rid of it.
Good luck.
bad accuracy
I bought a model 70 extreme weather in 300 win mag. It groups 2 1/2 to 4 inch groups at 100 yards with premium ammo. I've checked the scope bases and rings and they are tight. I've tried a Zies and a Nikon scope. I'm shooting off of a lead sled. Just a bad rifle!!!

I'll give you $25 for it right now. It's obviously only good for a tomato stake.
Give everything a check as described in this thread.
Shoot from a bench with either sandbags or a sled of some sort.
Concentrate on the trigger squeeze, don't yank on it.
Most people don't have enough shooting experience to shoot the bigger calibers, I don't know how much you shoot or what you shoot, I'm just throwing that out there, but with that in mind, could you be flinching?

Have you tried different weight bullets or all the same weight ? That barrel is supposed to be fully free floated and I would take a piece of paper and make sure it slides between the barrel and stock all the way up and down the forend. If it doesn't then something is off where the bedding is concerned, or the stock itself, they have a full bedding block and it should be in there sound and solid.

accuracy with Winchester model 70
I tried Remington Premier, Barnes Vor-Tx, Federal premium, Federal fusion, Winchester and Hornady. Bullets were 150, 165 amd 180 grain, I had someone else shoot it (a very good shot) and similar results. I shoot from a led sled. I've checked the scope base and rings. Tried 2 different scopes (Zies and Nikon). Winchester's website says it should shoot 1 inch groups with factory ammo.
