    I put a full sized stock on a youth model Winchester Model 70 .243 that I've had since I was a kid. I wanted to hunt with the gun this year for nostalgia. The gun always shot lights-out with 87 grain ammo. With the new stock on it, it will shoot the first shot to point of aim, then the next 2 or 3 shots will be about 8 inches high and right and continue stringing to the right as you shoot. The barrel is fully floated on the new stock all the way to the action. Any suggestions as to why it would be doing this?

    shaggy430,

    While free floating a barrel is usually conducive to accuracy with barrels with a fairly heavy contour, most light contour barrels come from the manufacturer with a pressure point in the forearm and seem to shoot better that way.

    Try sticking the action back into the old stock and see if it does the same thing. You never know..your scope might have had a coincidental faulure.

    If it shoots normally, then of course you can pretty much say that beyond a doubt that it is the new stock, however, something else seems amiss here.

    Did you just drop the barreled action into the stock, without any kind of bedding under the front portion of the receiver? ..or in the barrel channel?

    A free-floating barrel is great, as long as it's not on a free-floating receiver....

    I'm guessing Brownell's Acraglass Gel is what you need. Just a dollop under the front receiver/screw location; you probably encountered something similar in the old stock when you took it apart.

    I don't think that is the case. I put a brand new Redfield Revolution 3-9x40 on the rifle when I changed the stock. (The old scope was in need of replacement after myself, my brother, all my cousins, and all the local kids had been knocking it around for the past 25 years.) I bought the Revolution for the Leupold-backed lifetime warranty. Hopefully this scope will last a full generation of my offspring.

    Probably needs to be bedded.

    USSR has a good point. Drop it back into the old stock and see where the action and barrel contact the stock and compare this with the new stock. Either sand or acra-glass to reproduce the original bedding situation. That's my suggestion, anyway. Wouldn't be the first time I've had a dumb idea, though...

    Definately change it back to eliminate the scope from the mix.

    This. Untested scope. Try it on a different rifle and see if it works correctly. Just because something is new does not mean it isnt messed up or faulty.

    two variables done at the same time (scope & stock) eliminate one, test again..
    if I had to guess though, probably the stock needs to be bedded or the pressure point has changed
