Not to nitpick but it should be noted that the Clear Ballistic Gel isn’t the same as True Ballistic Gel.
True ballistic gel won’t be clear, it’ll be yellowish. The clear gel is super popular for YouTubers and can be bought cheap so it works great for videos. It’s also easier and less time consuming to make than true FBI calibrated Ballistic Gel, which has a fairly specific protocol to make. The clear gel is advertised as such, but it’s not actually calibrated to FBI Testing Protocols and normally yields higher than average penetration depths, as well as larger bullet upsets, with higher mass retention.
The video you posted shows a great representation of Terminal Ascent but it should be noted that they’re using clear gel. You’ll sometime see clear gel used in marketing videos and displays.
Here’s a video that sort of touches on the differences between the two. Where you really see the difference is when one starts to shoot through the other barriers and mediums the FBI tests against for their rating.
I still stand by my statement that Terminal Ascent is currently my favorite hunting bullet on the market today where a solid isn’t required.
