GNNC,
It might be tough getting the 7mm to go down the 223 barrel. I know what you mean though about the 10 inch 223. I had one up for trade for about a month and I got no replies. I didn't like it and I guess no one else wanted a 10 inch either. Buy a barrel CNNC

HOW FEASIBLE ? 223 TO 7MM TCU

Rechambering the barrel would not be a problem, from a technical standpoint, because all you should have to do is open up the neck area. The problem you would find is reboring, re-rifling, then recrowning the barrel. This would require quite a bit of machine time and would probably get pricey. Just sell the .223 and buy a 7mm TCU.
