[QUOTE="Jon A, post: 120271, member: 319"] You're right Dave, the faster you launch a bullet the faster it is going to lose velocity and energy. It's sort of a diminishing returns-type thing. I think that's what triggerfifty was trying to illustrate. For example, if you launch a 1.0 BC bullet 200 fps faster, you're going to have a 200-300 yd head start depending upon altitude, etc. This won't translate into a 200-300 yd farther supersonic range, but far less of a gain. Maybe as short as ~50 yds advantage in some cases as the two velocities slowly converge as they go down range. I [i]think[/i] that's what he was getting at. What got people was saying the faster bullet would have a 50 yd [i]disadvantage[/i] in the end. That's hard to imagine without some sort of spin differences altering actual BC's, etc. I can see the slower bullet pretty much catching up, or coming close too it for range vs velocity. I don't know how it would pass it though, with all else being equal. Maybe he misspoke. If not it'll be interesting to hear his explanation. [/QUOTE]
