DogmaDog, you're correct. To get the maximum effect from a suppressor, I need to keep the bullet flight subsonic to avoid the supersonic crack. And I'm looking to reduce the expanding gas from the ejection port. With the open bolt system and the Uzi's heavy bolt, the escaping gas/noise isn't much of an issue. But, I'd like to reduce this to make it as quiet as possible. At the same time, maintain consistent accuracy to about 30 or 35 yards for subgun competitions. Maybe this is asking too much? I may end up making a load that is real quiet and another for competition. I'm still reading and learning and will be purchasing a Dillon press from Brian this coming week (I've never reloaded before). I'm tired of buying expensive subsonic ammo to feed my habit. I also use the same suppressor on my M16/9mm and I can go through it rather quickly.
Regarding pressure signs, what does one specifically look for? I'm assuming bulged cases and or missing primers, but I'm unsure of this. I don't remember reading any specifics or a definition on the issue. When shooting factory ammo, I never had to pay much attention to this.
Good catch on the 0341. I was in a 60mm mortar section. Were you a groundpounder too?
Thanks for the info,
Dan
