Pneumatic != Powder Actuated. The former is propelled by air, the latter by smokeless gunpowder.

Besides, your video guy just had skill issues. These guys did fine with just a pneumatic, was your guy using a Ryobi or something lol? While that might not be as bad as a real bullet it doesn’t look like the clay pigeon 25yd away had fun.

If you want more penetration, increase the powder load from 2-3ish grains to something appropriate for your “bullet” weight (mind weighing some of those nails in grains for me?) Green and yellow aren’t even the strongest, let’s see what a purple can do (and also can someone weigh those powder charges for me in grains too?) Hell, let’s see what a 5.56 blank can do.
