No problem on the .22 Uzi conversation, but it's ammo sensitive as are most of the Uzi conversation kits. The Winchester Dyna Point, as you heard, is subsonic and is the only subsonic round that will run in my gun. It also likes a diet of Golden Bullets, both of which are available at WalMart in the 500 round value packs. I won't run any .22 ammo with the suppressor that isn't copper plated for fear of leading up the suppressor. The thing is fun to shoot when it runs well, and the 9mm can does a respectable job of keeping things quiet.
I need to spend some time with my Ceiner .22 kit for the M16 and find what kind of ammo it likes. I've only installed it a couple of times and it hasn't been as reliable as I'd like. I just need to tinker with it a bit.
Sounds like most folks like a noon start time for next month's DBS...
