Recently got my new build back from the gunsmith. It's a 6mm TCU, and after expanding the .223 cases and seating the rounds wouldn't chamber. Scratched my head for a week about what was happening but everything I tried didn't work. Finally tried running the case with seated bullet thru the trim die and, voila! Now I can get on with breaking in the new barrel and load development. Relief!
