Dave, that rifle looks really nice, you can definitely tell it is walnut, 7.62X39 is a real neat caliber, I've got a Russian AK-47, as well as a Ruger Mini-30, both are a real hoot to shoot. Well anyway talking about shooting, my rings came in the mail yesterday on that CZ, so I installed them and placed the Bushnell scope on it bore sighted it, and off to the range I did go. I took some of my handloaded 45grn JHP Remington, some loaded in H335, and some loaded in IMR 4198. That little rifle didn't care for either of the loadings at 104 yards according to my range finder. (It was absolutely calm with no rain in sight). Both of those loads were all over the paper using 5 rounds, The best groupings I was getting was just over 3.5".
Next I went to Hornady's SUPERFORMANCE VARMINT 50grn V-Max and that little rifle really started to perform. I had 3 rounds just about touching and the last two were right on top of each other for a 3/4" MOA. I had so much fun shooting those rounds, after getting it sighted in I started shooting at the head of my steel silhouette at 200 yards and even managed to put a smile on it, definitely not on purpose, but I do believe it is going to make a fantastic varmint cartridge. Note I also had some Remington 50grn PSP, that shot really well (MOA -slightly over MOA) also but the Hornady out shined them all. I do believe the overall length of the 45grn Remington HP were just too short and had to leap too far from chamber to rifling. Anyway I'm gonna have to do some more reloading as I've got quite a few 52 and 53grn. Sierra BT, and Hornady V-Max, and quite a bit of IMR4198 and H335 powder I need to burn up.
Incidentally that after mounting that scope I noticed that it only had about 1/16" when activating the bolt. Just might have to move the scope back but I've only got about 1.5" to move it back.
