Great video, as usual. I?m hoping you find a common 6.5 CM bullet that performs well in Grendel for hogs and other, more edible critters. I would expect good meat preserving performance on hogs would predict the same in deer.
I believe the problem with the lights is caused by their (internal) power supply. It produces a boosted (average) voltage that can maintain constant brightness over the battery discharge cycle by varying the on/off time of short pulses that are too fast to be detected by the human eye. This ripple in the voltage driving the LEDs causes ?beats? with the row/column scan rate of your camera. This effect is the same as what causes a spinning aircraft propeller photographed by a cell phone to appear wildly distorted. Unfortunately, I don?t have any practical advice to find a light with smoother output beyond trial and error.
Your hog anatomy and terminal ballistics demonstrations are excellent. I?ll gladly watch whether lit by Coleman lantern or flickering LEDs. Keep ?em coming!
