Very interesting test. If you had to guess, at 90 grains, what would be the velocity? Also are you certain at the lower charges that the bullet will or would preform as expected? I ask of course because my Optima loves 90 grains of Black Horn. I think even though its .40 caliber it would be an excellent bullet for deer in the hardwoods and fields around here.
As for #3 in your first group ... don't that just make your day.
