"You missed the part about the ice needle containing the tetrodotoxin." Gosh yes. I was figuring the massive blow by the needle would kill the victim by knocking him head over heels and the toxin was totally not needed. Duh-oh.

LOL the scenario: assassin fires then scurries after the sabot, which is painted in dayglo orange to make it easy to find! Hahahaa. Bullshit.

You say "Second-order factors at subsonic speed? I am an aerodynamicist by training, and you are talking through your hat. Air density is the only issue, and so long as it doesn't change dramatically over the path of the projectile, there is no problem. And even if it did change, there would not be much effect. Now you are grabbing at straws, since air density would affect ANY projectile weapon. A crosswind would be more of a problem."

Well bully for you Herr Doctor Mister Sir aeroboi. I am very glad you managed to make your way into weapons systems development despite a massive ego problem demonstrated here. I am merely a humble guy who studied physics under Feynman at a very good school, and obviously do not understand the physics of systems. Chortle.

Crosswind is exactly a second order factor, which for brevity I left out discussing, but I lumped such things together for now.

Shock waves. "No shock waves" "Any such harmonic response by the barrel would be less than for a regular firearm, since things are not happening as fast." Yes but not totally absent. A pneumatic gun still causes a rapid rise in energy and such rise does constitute a shock.

I merely cited barrels but it is the projectile behavior really at issue and an ice dart would vibrate upon being quickly pushed. At the start of the push it will compress, then spring back, and that can reverberate in a rigid body.

If the gun is CO2 based, there will be a rapid rise in pressure that may not be a Dirac delta pulse but close enough that there will be a high energy rapid rise pulse, and the system will have a transient response that can come awfully close to something that causes ringing. And ringing causes oscillatory physical behavior, which could well pressure a fragile ice structure. In audio and transducers, we deal with behavior with both fast rise pulses and somewhat dampened pulses. And you know what: they both make things ring, just at varying degrees. Any good speaker designer would probably laugh at your model.

"As for the scope, I have to chuckle." You do retardation really well. I didn't say he will be ignored for a pistol. The psychology of attention is such that not only could a pistol be perceived, but the additional strangeness of a scope on it makes it stand out even more. If the pistol is hidden, that defeats having a scope.

What was it Captain America said. Oh yeah, "I could keep doing this all day." Especially about 0.08 gram subflyweight projectiles and sci-fi claims about them made by possible government workers defending propaganda claims. Hey, what was the menu of the day at the CIA today, DRD? I hope it wasn't clam chowder with shellfish toxin.
