Besides the fact that my son isn't wearing his shooting glasses? Take a look at the rear scope mount. The mounts are 30mm Leupold rings and the base of the back mount has migrated forward about half an inch! I started out putting 3 rounds of Black Hills .223 Rem 52gr boat tail hollow point through the same hole at 100 yards and then the groups started opening up a bit. Didn't realize the problem with the mount until I got back to the house to clean the rifle. I dismounted the scope and took a look at the rear mount. The Leupold mounts do have an off-set stop pin in the rear ring to fit the CZ. The pin was not sheared, but it had retracted into the base of the ring. OK, just need to screw it back out, but nooooo! The pin is not threaded and the hole doesn't extend into the inside of the base of the ring. There is no way to screw or pull the pin back out. So...
I cleaned the rail, the rings and all the screws with acetone, and LocTite'd and torqued all the screws when I remounted the scope. If the rear ring migrates again, I am sending the rings back to Leupold. But I have the week off and while I am up in the mountains, I want to keep shooting.
One other discovery -- in a drawer in the"mud room" there is some sort of pull-out device that came with the cabinets. I don't know what it is -- I have never seen it used. But it seems to make a really nice pull out bench for cleaning my rifles and working on scopes and such.
