So, I ended up making a can (form1) and did a few test cycles today with cci suppressor rated ammo (950fps I think?). Anyway, definitely quieter with the can on vs not but… I dunno,e expected way more. 5.5" barrel into 7" can (35mm OD). You could shoot this all day of course with no ears on, but it’s just not doing it for me.
What is currently the quietest can sailing currently? I original was going to try something from the FTN line but ended up going down this rabbit hole of making my own LOL. I mean, it did work so I’m not going to be super hard on myself…just didn’t work well enough for what I’m looking for.
People often have unrealistic expectations for 22LR “suppressor” ammo. It generally has just as much power as conventional ammo (hence just as much “report”) but uses a heavier bullet to ensure it remains subsonic. Since most 22LR ammo is already subsonic out of a < 6" barrel, the suppressor ammo buys you nothing in terms of sound reduction.
Note that suppressor ammo sometimes runs a little cleaner and may be overall higher quality/more consistent than bulk ammo, so it’s not necessarily a bad choice … just don’t expect it to automatically be more quiet.
