It looked more like the actual gas made the hole... not the bb, but I'm stupid...

If you can coax the BB into surviving its short and violent trip out the barrel, it'll probably go through 1/4" steel plate without much troubleI'll make an airsoft barrel for the ETC when machining is finished. If around 5km/s and twice the energy of a .44 magnum doesn't do it, nothing will.
In free flight, the round would have traveled roughly six feet per frame of video (at 1000 frames/s). Even with excellent lighting and a perfect camera angle, I doubt it would show up as even a faint green line on a single frame. Considering this, I'm not sure how one could surmise that it "looked like" one thing or another penetrated the coin. However, consider the facts: the total body of propellant gas weighs less than the projectile, and only a small fraction of it would be moving out the barrel at the same speed the projectile is. Also, the projectile is solid, and still a good deal denser than the gas.
The main body of the propellant gas, the incandescent jet which extends through the (empty) holder arrives, relative to the timescales considered here, long after the projectile has come and gone, punching through the target and ripping it out of its holder in the process. The damage to the table behind it suggested that the dime impacted it at between 50 and 100 m/s, consistent with the momentum it would have gained from the impact and fast moving front of the propellant gas. That incandescent jet is shooting through an empty hole in the holder, where the dime used to be.

If you want, I can mail you some .2 gram bbs. I think the reason you aren't getting through is because .12 gram bbs are usually shoddily made and have a large air bubble in the center causing them to crack easily.
Yeah, it's that important.
Not getting through what, precisely? The 0.12g BB went through just fine on the last shot, as the pictures on the video indicate.If you want, I can mail you some .2 gram bbs.
