Working with the available space and twist rate to determine your nose shape and bearing surface length is going to be a major aspect of getting what you want. Between the odd bore diameter and the chamber modifications many of these Cadets have had, we're all "off the reservation" to a greater or lesser degree. I doubt an off-the-shelf mold is going to leave you with the desired warm fuzzy feeling in this case.
