Re: HELP- I WANT TO IMPROVE ACCURACY OF MY SAKO!!
I agree with what the others say.
I would first try some reloading and with quality components and a good job you should be able to reduce your groups.
However, it is also true that an accurized receiver/bolt and a good quality button or cut rifled barrel will improve not just accuracy but what i guess is more important, consistency and therefore reliability. You do not just want your rifle to shoot a small group every once in a while, you want it to do the same always.
As for rebarrelling, you have to consider what kind of hunting you are going to do.
