[QUOTE="KYpatriot, post: 1138917, member: 48028"] [b]Re: What external ballistics topics would you like to see explored[/b] Bryan, I have enjoyed your books, and appreciate your efforts in improving the long range shooting community. At this point i believe you have done such a good job on the major external ballistics factors that you are reaching a point if dimishing returns there. Frankly, we need the same sort of effort concerning internal ballistics. I would like to see someone pick up where Harold Vaughan left off, and to update, further explore, and expand upon the internal ballistics factors in his book, but in a way that provides good guidance for the shooter, as you have done with external ballistics. For instance, an indepth study comparing and contrasting the various factors affecting extreme velocity spreads and how to minimize them. Shooters are using an experimental process, basically try and see (just like we used to do with external ballistcs) to develop loads when a better understanding of the variables could lead to a smarter, more systematic approach. What is the best way to throat a barrel, what lead angle, what neck design? Where is the data on what affects neck tension, how much we want, and why? Is the answer to that powder specific? What causes a rifle to like one load over another? What does changing the seating depth do, and how can that be used? How do various primer makes affect a cartridge, all other things equal? What is the relative importance of each of these factors among others such as neck turnng, primer pocket uniforming, annealing, etc. We desperately need a volume that consolidates and validates the "conventional" wisdom on these topics, using a data driven approach to separate what we think we know from the truth. Is the optimum barrel time theory correct? Is the ocw method the best, or ladders, or something else? What about bullet coatings, moly vs TI vs HbN? Barrel profiles and lengths? Case neck treatments? Suppressors? How much do various things affect pressure? How to better read brass or other signs for pressure, etc ec. Many, if not the fact majority, of serious long range shooters load their own ammo in an attempt to control these variables and more, and we have little understanding of their relative importance and their interactions. Unless you can figure out a way to measure wind velocity components accurately using a laser or somethng, I think you have covered external ballistics to the point that much that remains is certainly in the "noise" of the inherent dispersion of the average load long range shooters are using.
