I got all three diameters in the 5 weights from H&N on Friday, will be testing them with Laity shortly, the 41g .25 is of particular interest of course.
Hmm, what was the MV and distances for that BC calculation? I'd expect at least 0.095 for MV > 10m, and probably 0.09 from MV > 50m (judging by the projectile structure in the photos that I have seen).
