[QUOTE="Brown Dog, post: 120729, member: 1622"] Joining this one rather late, Nearly spilt my coffee when I read theories along the lines of : "for 2 identical bullets, the one with the slower MV will overtake the one with higher MV" [img]/ubbthreads/images/graemlins/shocked.gif[/img] For my money Bill Bailey accurately summarised the flaw in the theory: [ QUOTE ] The air resistance may be more on the faster bullet, but it still is starting faster. The slower bullet is going 3300 fps @ the muzzle. The faster will be going 3300 fps x # of yds down range. Now, all things are = except the faster bullet has a sizable head start. So, how does the slower bullet make up x # of yds?????? [/ QUOTE ] ....I think people are getting confused by 'averaging' the energy loss figures for the 2 bullets. Yes, taking the muzzle as the start point, over identical distances, the faster one will have a greater average energy loss ....its average will have been skewed downward by the inefficiency of its early flight (when compared to the slower bullet)....it will, nevertheless, always be faster. [img]/ubbthreads/images/graemlins/smirk.gif[/img] ....either that, or we'd better rewrite every artillery firing table ever written...think of all the money that's been wasted putting charge increments in to boost a shell's MV (and therefore range), when we've just learnt here that a lower charge/ lower MV would have made it go further [img]/ubbthreads/images/graemlins/confused.gif[/img] [img]/ubbthreads/images/graemlins/shocked.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [/QUOTE]
