I never used a PCP for target work. That was the Weirauch HW97, which is fixed barrel, underlever spring & piston, with an auto safety and anti bear-trap mechanism to stop your fingers getting chopped off by the loading port cover.
The HW 100, I used for rabbits and pigeons. Semi-auto, silent and 70+ full power shots on a full chamber.
@Dyslexic cnut. You got an HW 100? Mine is the walnut sporter stock. I'm not keen on thumb hole stocks.
