Hi folks: Here's what I did to fix the exact same problem you two seem to be having. Generally speaking the CZ 527 is one tremendous little rifle. Mine is a constant 3/8 inch three shot rifle with my 50 grain handloads. It had problems feeding exactly the same as you two describe when I got it. I stumbled across the fix one day when looking at the guts of the CZ 527. To see if the problem I had and your problems are one in the same. First, take the barreled action out of the stock as well as the bottom metal. Be very careful of the magazine spring as this little fellow is very easily broken because it is brittle. I speak from experience on this. So when your barreled action and bottom metal are free of the stock put some cartridges in your magazine. Next, fit the barreled action and bottom metal together without the stock. When the two are together install the front screw until it bottoms out and is snug. Next, install the rear screw until it too, is snug. Next, put the magazine into the bottom metal. There is a metal lip on the magazine about half way up on the right side. When this lip hits the perfect spot in the bottom metal the magazine spring will push the magazine so it snaps into place and the lip will push into a rectangular hole in the bottom metal. It is awkward, but try working the bolt handle now and cycle bolt. If you had the same problem I did, it should cycle perfectly and pick up cartridges like it was designed to do. If it does not do this, then we have different problems and I cannot help you. If, however, it picks up cartridges like it is supposed to, then the bottom metal stock recesses were not inletted deeply enough. To get a rough idea of how much I had to remove I counted the number of revolutions needed to snug the front and back action screws with the action and bottom metal out of the stock. I wrote the number down for each as I find the older I get the more I forget. I then put the action back in the stock along with the bottom metal and counted the revolutions again. I'm not smart enough to figure out length based on revolutions, so I had to remove the action and bottom metal from the stock again and install the screws to match the number of revolutions needed when the action and bottom metal are in the stock. A set of calipers can show the difference, or, a very ballpark figure for the amount of wood to remove from the tang areas of the bottom metal. I used a dremel tool and removed little wood from the front and the back, then put the bottom metal and action back together again in the stock to see if it is any better. At some point you will hear a click when you install the magazine into the rifle. You must be very careful in this process of not forcing the bottom metal into the stock and bending the magazine spring in the process. Through trial and error you can eventually remove enough wood so that the magazine sticks far enough into the action so the cycle works correctly. It actually made my rifle cycle better too. Hope this helps you. If you go too far you can build the bottom metal tang recesses up again with small dabs of bedding compound. However, by removing just a tiny bit of the same amount of wood from the front and back tang areas at a time should produce the effect you want. This is a fairly easy process to do. Good luck ...
