I was looking over Lyman's current offerings and saw the Lyman 311679. In Lyman's words, "A new 30 caliber 195 grain gas check mould designed by John Ardito. Features a bore riding nose which tapers up to meet the driving bands. " This is indeed new to me. Ardito is a benchrest shooter is he not?
I did a forum search and found one reference to it in a 300 Whisper. Anybody else have any experience with this design? Wonder if its worth a try?
