would it be possible to shoot each arrow with the same head? Or to test each of the two heads attached to the same arrow?
Yes I could, but that would open up another can of worms because the arrows are currently spined for the heads and if I swaped heads then I would have one arrow over spined and one under spined
Also, I'm not convinced that the penetration an arrow displays on a broadhead target necessarily indicates what could be expected on game; since almost all of these targets stop the arrow by exerting friction on the arrow shaft.
That is true and I totally agree but my tests where for mainly arrow flight and to see what the drop was between the 2 arrows I was expecting the heavy head to drop but was surprised when it didn't.Oh and the human element was taken out of the shooting
Got some hogs in your neighborhood

Unfortunately no I dont but I do plan on going after some again when the weather cools down.
