I'm relatively new here and have reloaded .45 successfully. I am now using RCBS carbide dies to load 9mm 125gr Penn RNBB lead bullets using WSF (I have a bunch of that around..like 15 pounds, and 1,000 of those bullets) I posted here a long time ago about COAL and was cautious about making the cartridge too short as there is a lack of data for the WSF. Factory RN hardball ammo Fiocchi 9mm measures 1.156 while the sources I look at recommend 1.169 COAL (I assume that's the maximum?) Anyways, I've got her down to 1.135 and it still won't pass the "plunk" test in the barrel (nor will it in my STI Guardian.) Sure I can go shorter to pass the "plunk" test, as I'm assuming the very round nose of the bullet is preventing the seating, but how do I know that? I can make up new dummy rounds but if I get real short to get seated will I blow off a limb even at the lowest starting measure of 4.0 g of powder? Any help is appreciated and I'm sorry for my lack of experience, I simply don't know anyone who reloads.
