Bill...I have the same reamer...if you want I will ream a Wilson straight line seater for you...I recommend...a 30BR Wilson seater cut of .325" and a "Robinett" reamer run in for a perfect fit...
If interested PM me ... I have a standard Wilson seater (non micrometer top) that I can modify for you if you don't have a 30BR seater...
