This is a quick video I used to baseline some subsonic loads I have been working on. It is not as good as Elite Ammunition's QuieTOR, but it works. Do not attempt to shoot reloads based on this data through a full length carbine or AR-57! If you are curious about the 5.7x28 round, visit http://fivesevenforum.com/
sweet set up! what type of flash hider is that? How do you attach your Spectre to the PS90? I would like the same set up.
