OK A few years ago I went shopping for a new .22. Reason was is that a group of guys that I get with once or twice a year and I were doing back yard comp shooting. I noticed that some of the guys shooting bolt guns were doing much better than guys with semi's that I know are better shots. So I bench tested my Remington semi against an old Winchester shingle shot bolt gun that I got years ago as a training gun for my kids. Accuracy at a given range was about even but a varying ranges the bolt gun beat the semi hands down mostly due to bullet drop. A semi uses part of the power to blow back the bolt. After 50 yards the semi had a lot more drop than the bolt.

I was looking for a good quality gun because I do a lot of shooting and wanted something that would last. I did some research and got a CZ 452 (CZ USA) sporter with a decent 4x scope. When I went to zero it I dialed it in at a measured 50 YDS. Shooting from a bench, off a rest, 10 round groups you could cover with a dime. I was very pleased! So I decided for the comp shoots (we use 10 gong tgts, 2 1/2" placed from 25 YDS to 125) to zero at 100. Sub MOA 10 round groups. I figured I was just having a real good day. So I shot groups several time over several days......all with the same results. Then I saw an article from a shooter/writer for a gun mag. He described the CZ 452 as "target rifle accuracy from a sporting gun".

For zeroing I use a Lead Sled rest and a bench. I always use this setup for everything when zeroing. I know that I have, within reason taken most of the human factor out of it. Basically all human interaction is sight picture and trigger. After that I know what the gun can do so if I miss I start looking for what I did wrong.

So as others have said, Try it again. The bipod isn't the problem, it's the unsupported butt that's wiggeling around I bet. SO set up where both ends of the gun are supported (not off some rickety table, something solid). Set the scope back to 4 or 5 power. That way you don't see the movement and you are not tempted to chase the cross hairs. Now shoot at least a couple of groups. Don't try to zero, aim dead center bull and shoot. All you are trying to do is see if the gun can shoot a decent group, not where they are hitting on tgt. Once you are confident that the gun holds a good group then zero for what ever range you will be shooting at.
