I've been reading on the interwebs about reaming custom dies. Most folks say that using the chamber reamer to make a sizing die does not work but then I came across Newlon Precision where they say that their dies are used with the same reamer used to cut the chamber. So what is the correct answer? Another thing lots of folks say online is that most commercial reloading dies are made on a CNC lathe, which makes me wonder with the chamber isn't cut the same way?!?!
