Hi all,
Just re fired my CZ550 Premium last week...first time in a year! Originally tried the Millet rings included with the rifle but they wouldn't stay tight. The receiver foot on the back left didn't mate up with the receiver cut out so the scope would move. Ordered some Warne rings and installed the thing myself. These are outstanding rings in my view...anyway, boresighted the old fashioned way by removing bolt and sighting through the bore until I could see the target, then adjusted the Leupold VX II until crosshair were on and presto...first shot was 3" low and rt of bullseye. Fired again and the spotter said "Uh...I think it hit the same hole!" Moved to 100M and fired 3 touching then zeroed at 200m. Also took some shots at the 450M steel gong just to see what would happen. Aimed about 24" high and bingo!
Gotta love this rifle! I let the range guy take some shots and showed him the "set" trigger...wow! was his reply.
Bottom line...don't use the Millets
