can a 30tc be rechamberd to 308win ?

The short answer is yes.
The longer answer is yes but there will have to be a significant set back of the thread tenon in order to have the narrower shoulder of the .308 go deep enough to clean up the chamber.
The T/C shoulder is 0.464" while the .308 is 0.454".
Best.
Then the answer is definitive no.
There is no provision for set back on the T/C Encore barrels and the standard .308 reamer will not clean up the .30 T/C chamber at headspace.
You can use the suggested .30-06 Improved which will push past the shoulder diameter as Charlie suggests or use another great cartridge like the .30-284 which will stay as a short chamber but clean up the entire .30 T/C completely from the start. This is a .284 Win. cartridge necked up to .30 caliber. It can be reloaded to work as a .308 up though nearly light magnum performance, depending on the powder and bullet combination.
Best.
I purchased 4 of the very first high grade wood ICON's a few years back on fire sale for $399.99 each from CDNN. One is for me, two are in the hands of a couple young men that I love to teach the ways of the outdoors, and one is in a safe place for a soon to be 4 year old, that I will be an ambassador for when he is mature enough to use it.
So the simple question, is why?
Most likely due to ammo availability and cost.
