Wow, excellent test. I think that clinches it for me. 0.12g pellets have significantly less damage potential than heavier ones.
However it does look like the 0.2g, 0.28g have nearly comparable damage potential to the 0.43g pellet which is a huge lot heavier. Are all those shots chronying in at equivalent energy? I'm wondering if the dinky 0.12g pellets are coming out with significantly less energy than the heavier ones indicating some sort of weight based limit where lighter pellets are not able to take on as much energy as heavier ones.
