I had similar problem with my sons .243. Luckily I bought it from Davidsons, they had them barrel it. We havent measured the groups on it yet but at least we could sight it in. With the first barrel at 100rds some shots would be off paper..

I still need to send in a Cabelas 12FV 308. Im out of left adjustment and it is still 1/2 inch off. I am fearing that Savage will tell me the same thing and this time I get to pay for all the shipping. It might be cheaper to just re-barrel.
