So Old I'm Losing Radiation Signs

So, I was watching the GURPS Fallout promo and I saw an interesting thing.

Namely, in higher res (480p), it's visible that the Assault Rifle is probably named "Colt Rifle" and the damage is 7d (in contrast, Desert Eagle has damage of 3d just like in GURPS High Tech).
What's so interesting about it?
In GURPS 3rd ed, it's a damage value of 7.62x51mm, so it looks like it was supposed to be a full calibre rifle.
To make things even weirder, both the trailer and the only inventory screen show .223 ammo, but no .308 or 5mm ammo.

Any thoughts?
