Found a few that look pretty close to the one on the right in the pocket predator gallery. See link below.

Closest I see looks to be called a Honey Micarta Target. I'm guessing that "Honey Micarta" is the frame material, so the frame might just be called the "Target"?
The one on the left is an earlier iteration of the Hathcock Target Sniper, a design originally named the Target Master.
Someone else will likely know the definitive answer. Who knows, might even get an answer from Bill himself.
