CIP prescribes (with legal binding force in CIP countries):

34�56'58" for cartridge
35� 5' 6" for chamber

Carcano

Thanks for your reply. Does CIP specifications indicate if the shoulder angle you report (~35 degrees) is "one side" or a "two side" measurement(single angle using both shoulders with a converging point somewhere in the case neck/throat area)?

I ask this as the diagram that was provided in an earlier post clearly indicated a "one side" (single) shoulder angle measurement, based on the major axis of the cartridge and one shoulder, which had a value fo 17.5 degrees. If you double this, you get 35 degrees.

I'm not splitting hairs, I'm just trying to finalize this. Perhaps the answer is right in front of us. We just need to specific the basis of the measurement. If you can check on this, I sure would appreciate it. Thank you very much in advance. Look forward to the findings. I need to get some dies soon so I can load this CZ 550 up.

What dies are anyone else using on for this rifle's 9.3x62 chambering?
