Re: rechambering
Like Boltripper said above. You can chamber a 30 cal to 30 cal or a 243 to 6mm if there is the nedded room for the barrel to shoulder against the receiver / recoil lug. In recutting the same type chamber I usually use 1/4 to 1/2 inch to cut out the burned throat area. The main problem you will have is that you are going from larger chambers to smaller chambers. This means you will have to sacrifice more of the barrel to be sure to get the chamber right.
You need to really check your bolt faces for the new chamberings.

Can I rechamber a Ruger #1 from 7.62 x 39 to a .308?
I think I should. </div></div>
You're looking at a more powerful cartridge. That's a rifle I don't have a lot of experience with. I might consider selling that one outright and buying a new rifle.

Re: rechambering
It completely depends on the barrel contour. If its a straight taper with 4" of straight at the breach it can be set back at least 1 time. Problem comes in when you dont have enough breach to hold on to with the spider or 4 jaw.

Re: rechambering
I concur with Victor.
One of the issues is that the 7.62X39 is made with at least two different bore diameters. Domestic barrels <span style="font-style: italic">tend</span> to be made to fit .308 diameter bullets, foreign ones for the .311/312" diameter.
