Some specs on the 7.62x25
 

After telling a buddy of mine who also owns a CZ52 (I told him about them) and the 'doubting thomases' here, he did his own tests. Here are the results.

Jim- avg fps / 1224 rds 1558 fps, sd ONLY 22 es of 48, groups of 2 moa on your polski spam-am. no cleaning, no salts. order me 2 cans more boss, these are better than any of my match ammo! NO FTFS AT ALL.
penetration through 2" "nigga" jacket, jeans and t-shirt plus a 350 lb hog (who died at tom's from the weather) with innards resulted in more damage than 762 39 fmj (not soft points tho). just a tad less than the sig (but not the baseball wound channel of my sig's gold dots), and as bad as my handloaded 75gr 5.56 barnes tsx. car door or glass for the 25 is unmatched deadliness unless you go to a rifle caliber. exit wounds in all tests were baseball sized with a golf ball wound channel starting at 1.3cm of flesh contact. Devastating to say the least, and reliable. I've found the holy grail of pistols with your help Jim - thanks once again. forget the sig except for home use and ccw only because it is smaller! the autopsy was jello vitals.

He lives in a different state from me. But loves his CZ52.

Some here won't believe this. GUESS WHAT? Don't care.

This isn't up for discussion or debate. The specs ARE WHAT THEY ARE. Believe or don't. AGAIN, I don't care.
