New firing pin spring installed. Today, I put about 100 rounds down the tube at 50 yards...Lapua Center-X (a known accurate lot); Wolf Match Extra (also an accurate lot); Eley Club; Geco Rifle; RWS Target Rifle.

Groups shrunk slightly, but nothing to write home a about.
Still have a flier or two in a 5 shot group.

Different scope tried---a 24x Fecker.
