Regarding the video, finally watched it and all I can say, just don't draw any conclusions based on it.
Not judging the bullet, there's already testimonials in this threads from members, that are worth considerably more (than the video).
Having shot match bullets into different media, and also using CB gel for this and other purposes, all I can say firing a single (match) bullet into CB gel doesn't provide adequate info about the variance on real game.
Shoot 3 bullets that act similarly, I start to believe there's a pattern. 5 bullets, even more. At somewhere about 7-8-10 similar results in a row, I will vouch for it. Match bullets that is, and this includes Nathan Foster's modification i.e. shortening the bullet and thus enlarging the hole / meplat (this part of course goes only for HPBT not tipped ones)
The CB gel is a subject on it's own. I have a hunch that it doesn't act like calibrated gel, at least on lower velocities (subsonic). But proving this takes time, effort and money. It's been some years since I tested CB gel and haven't felt the urge for further tests. Regarding the video, e.g. total penetration would depend on the resistance the gel provides when bullet has slowed down to SS velocities.
