You should refer to Alliant Powder's website for its load data. Alliant Powder is only powder maker I know that shows separate load data for a military action rifle (such as the M38 or M96 Swede) and a commercial action rifle. What you will discover on Alliant's website is basically this. What is the max load for a military action for one of the recommended 6.5x55 Alliant powders is about the start load for a Commercial Action rifle such as your CZ. I own a M38 Swede military rifle and a sporterized Swede 96 action rifle, both 6.5x55s. Also own a Savage Action rifle I rebarreled to 6.5x55. I'm very careful in not mixing up my Alliant based reloads in these rifles.
Gent I've shot with for years at range we're members is a big 6.5x55 fan. Owns a 6.5x55 (SKAN?), which allows him to drop a little more powder in his brass. His rifle has a Remington 700 action. Basically, whenever he is working with a new powder/grain bullet, he generally starts at whatever is the MAX load (not Alliants for commercial actions) and works up from there until he gets pressure signs. I chuckle at him, but he gets some very high velocity out of his 6.5x55......much more than me.
