Reread my post Butch Alex and many others have tried the modifying die thing, IT DIDNT WORK.
Why do you think he worked with Bullet Central to make dies to match his reamer, now Eric Cortina does.
That is why he redesigned his reamer.
The point is use the best tool for the job, there's complaints all over the place about PRC sizing issues all you have to do is look or ask gunsmiths who's built a ton of these PRC's instead of trying to fix a problem after the fact.
Again you cannot size brass smaller than what it is brand new no matter what die you use.
Google " PRC die problem" there will be many post you can read about it and what the solution is
