A long time ago, I had dinner with Nick Jenjinson at a Field Target event. A few months later his NJR was first revealed. He is a true gentleman. The NJR became a favorite in the Field Target community.
BTW, there was a time Nick put pistol barrels on TX200 for Field Target. They were effective.
BTW, my PCP ZM2002 (Anschutz tuned by Allan Zasadney) barrel is only 14 inches long with a FULL 2 inches into the receiver.
Thomas accurate rifles are also short and can compete in Pistol class Field Target.
