Nice picture, Rob. Looks like they changed the profile a bit too, in addition to a new tip material. Wonder if the new tip by itself didn't have the effect they were looking for, so they redesigned it for a longer, slimmer profile. I guess we'll never know how much the B.C. improvement is related to tip material and now much is profile/aspect ratio related.
Thinking about it a little, and based upon my knowledge of aircraft, the tip of a bullet thats going Mach 3 has to be seeing temps of at least 500 degrees F albeit very briefly. I wonder what kind of thermoset plastic can withstand that kind of temperature AND be moldable too?
Any physicists in the group that want to chime in?
