6mm ppc flash hole. No I said flash hole.
Looking to get a 6mm ppc, but see in the load book that there is a large flash hole and a small flash hole. The hornady book only list one style. (not sure which as I just moved and can't find the book.) Is one style the norm and the other old, as is the case with some of these things or is this something I need to read up on? As always thanks for your time.
