In the white paper by Emery he doesnt show a comparison between an original amax, and an original shape amax with the eld tip substituted. The graphs are comparisons with nosler lrabs, so it isn't apples to apples as far as the tips are concerned. I also agree with you about the heat transfer. Its difficult to capture fired bullets without damaging the tips due to impact , thats why i thought of the wind tunnel, but it would be interesting to see the difference side by side if it could be done with a soft trap of somekind.  Ive seen paint damage on aircraft due to speed, in fact speed limits on the F-15 are heat related...but of course we are talking about much longer time of flight, and they arent made of plastic lol.</blockquote>
