Dear Sirs, 
Does somebody know what is the reamer size to ream an O-1 (rod) point up die? I want to make a .224 and .308 point up dies. 
I know that these reamers should be a little undersize, but how much is this undersize? I will later, of corse, use diamond paste to have a mirror finish. 
Thanks for any info 
Paccini
