There were two different velocity penetration tests with the 325 grain Safari Solid on the same day.
Velocity Impact 2472 fps = 52"
Velocity Impact 2226 fps = 51 & 52"
An extra 246 fps did not provide much to any additional penetration in the test media.
I saw other examples where the 450-gr Safari Solid gave similar penetration at 2200-ish fps impact and 2400-ish impact. I attributed that to higher order impact media getting more resistant at higher velocity, like real game animals. Could be variability in the impact media beyond Doc M's control. Overall we are seeing a picture of speed increasing the penetration, but that doesn't mean I have stopped scratching my head and wondering about statistical significance of 2, 3, or 4 shots. Maybe one more bullet test is needed. 400-gr/.458 with .650" NP versus .750" NP at low velocity and high velocity. Heh-heh-heh. It sure is hard looking the gift horse in the mouth, but eventually we must.
