Hi I've recently bought a CZ17hmr rifle. It came factory threaded and my .22lr suppressor is rated for the .17hmr and it fitted really well. However....in the last week, much to my surprise I started to miss bunnys by as much as a 6 inches!! (lots of 'pinging' around them!) So, took the rifle to a nice long field and set up my target at 100yds....and didn't even hit it!! At 50yds I wasn't just missing....I was poking holes in the wood around the target completly randomly! I removed the suppressor and.....5 shots in an inch! I was curious if anyone else had the same problem and if they managed to sort it out?
