Had my cz452 out and was trying diff. subsonic rounds to see which ones were to it's liking. All shot really good,,, and then tryed the 60 gr super sniper
and at 22 yaRDS THEY ALL TUMBLED!
Had shot they in my heavy bbl Savage and they shot great. It must be too slow of a twist. Am thinking I got lucky and didnt destroy the Suppressor.
Something to think abnout.
