[QUOTE="Michael Courtney, post: 927212, member: 28191"] Thanks. The JBM site has the total lengths for a lot of bullets, but I don't know of any repository for the plastic tip lengths. We buy our bullets like everyone else, so we're not really interested in buying and measuring lots of plastic tip lengths. We're reluctant to pass along info we have not verified. It is simple enough to measure the bullets you own, and to at least get the total length from the manufacturer or JBM for bullets you are considering. The calculator at the JBM site is an implementation of the original Miller formula and the adjusted formula for plastic tipped bullets. It should give the same Sg as the spreadsheet, except the spreadsheet also includes the case of open tipped match bullets. The total length of the 53 grain VMAX is 0.829" and the metal length (or full density length) is 0.688". Many plastic tips are in the neighborhood of 0.15" long, so in the absence of a precise measurement, that would be a reasonable estimate. [/QUOTE]
