Hello, just curious if there is a solution to the problem of the barrel sliding side to side in the stock, even when I tighten up the the front bottom screw that holds the barrel lug dovetailed to the barrel dovetail. I find that movement annoying, I also bet that the tighter the screw, the point of impact will move downward (not too crazy about the way the stock it attached to the barreled action, instead of both screws attaching to the action, the front one is attached to the barrel through a barrel lug).

The barrel lug slides freely in a dovetail on the bottom of the barrel.
Remove it and take it to the hardware store with you. Get a metric socket head (allen head) set screw that is short in length. We will use this to secure the lug to the barrel. A M6x6 is recommended, and can be supplied by FastenAll
Now thread the set screw into the lug but do not tighten it yet.
Put the action and lug into the stock. Screw the action screw into the lug just a little and also finger tighten the rear action screw.
Now using the front screw center the lug in the stock hole. Remove the screw and tighten the set screw this will secure the lug in the dovetail. (Later See #2, it is recommended to 2 business cards on each side about ¾’s along the barrel).
Next, you do NOT want the action screw to touch the set screw in the lug.
So to check that put a drop of fingernail polish on the end of the stock/lug screw, let dry and then thread into lug and tighten. Remove the screw and look at the fingernail polish. If it touched the set screw the fingernail polish will be marred or have marks on it. If it touched you will need to grind or file 1 or 2 threads off the screw to shorten it.
I have found that my CZ’s shoot the best with 24 inch lbs of torque on both the front and rear action screws, yours may vary. (Take your torque ratchet to the range).
Start at about 18 in lbs and shoot some 5 shot groups and try different settings until you get to the “Sweet Spot”. Good luck and have fun!
