The tech guy said that the nitride burns off and doesn't leave anything on the barrel like Molly does... who knows if hes just pushing his product or not. 243's life is so short anyway I'll just shoot whatever I can find available.... hah

BTW, I was passing info about the DTAC to the JBM website owner (which he graciously added to his ballistics tool BTW) and found that after we called Superior Shooting Systems, their BC claim for the naked 115gr was .575 intead of .585 which seems to be published online in a few places. Since the .575 number was less than I had in my spreadsheet, I rechecked it and sure enough it looks like they have reduced their original BC claim.
