jef Posted July 12, 2009 Report Share Posted July 12, 2009 Hi all, Having major problems getting my newly aquired .223 CZ527 to zero. The shots just won't group at all. Two shots might be within an inch of each other then the third is off the target! It came with a T8 which since removing has improved matters. I have since noticed that the baffles are disintegrating. The mounts are good, and also the new scope is solid. The barrel is floating free of the stock also. The only thing I can see is a very sorry looking crown on the end of the barrell. How much will this affect the accuracy?? Ammo is Rem Accutip 50 grain. Thanks for any tips James Quote Link to comment Share on other sites More sharing options...
Billy. Posted July 12, 2009 Report Share Posted July 12, 2009 I would look at changing the weight of your ammo. Garyb had spent loads on ammo and trying to zero his .223, only to find his rifle refused to group his 54grn (I think it was that) ammo. If you feel like getting rid of the T8, drop me a message :yp: as long as it's 1/2"UNF. Fingers crossed it gets sorted for you Quote Link to comment Share on other sites More sharing options...

Baldrick Posted July 12, 2009 Report Share Posted July 12, 2009 The only thing I can see is a very sorry looking crown on the end of the barrell. How much will this affect the accuracy?? Very significantly, is the answer to that question. I experienced exactly the same problem with a second-hand rifle recently, and re-crowning and re-threading solved the problem absolutely. Don't waste ammo trying to investigate further - get a competent riflesmith to look it over. Quote Link to comment Share on other sites More sharing options...
