Actually,
I only have one shot of data for this bullet (problem with rifle misfiring).
That's not really enough to establish the BC (G1 or G7) with much certainty. Given it's shape, and the limited info from that one shot, the G7 is a better match.
I hesitated to even report data for this bullet in the book, but figured something is better than nothing. If you (or anyone else) test it, I'm interested to know how you find the match.
