I have two Savage sporter barrels that I need to have threaded to run a Harvester on, one is a 243win and the other is 270win. I will be cutting both barrels back to about .625" outside diameter and need to know what threading will work best for each caliber.

Thanks. Do you know if 1/2×28 will work with both bore diameters?
 
You may consider threading a permanent stub onto each barrel. Then thread the stub for the muffler.

Best would be 5/8x24 for the muffler.
 
My AR is and Tikka will be 5/8×24. I have another 270 barrel for the Savage that is a heavy sporter I could use and thread it 9/16, but not sure if it will have enough to go 5/8. I will have to take some measurements when I get home.

Are you referring to something like this?
