17/06/07: Laser measured 118 yards.
John Bowkett BSA Hornet .22 JSB Exacts 876 fps 27 fpe at last chrony test some weeks ago, BC 0.0362 at "Pinelea". Sight height 1.5 inches above bore.
Sight raised 20.24 MOA from 50 yards zero as per Chairgun. Hilltop is approximately 2,000 ft ASL, the Chairgun chart is for 3,680 feet ( at our farm "Pinelea" near Uralla ) which could account for the slightly lower group centre POI.
10 shot group plus the four sighters penciled.

........ Kind regards, Harry.
