Re: [Phys-l] Ballistics divertissement



"I think they have the protocol wrong. Both military and civilian firing squads had one rifle loaded with a blank and the rest with live bullets ..."

Yes, and I think the reason is so all may think they didn't kill the victim, which implies ....


I asked an employee at trigger hill -- he immediately pointed out as stated in this thread, the smaller charge. He thought there would, all being equal xcept the bullet, be a difference until I pointed out rockets don't use bullets. Then he told me the "gun" shop in Watsonville rents and has their own range. He also agreed immediately that if the difference was slight or non-existent the perception would mirror the belief. [I should have asked if he got a good grade in Physics!]

So if this thread doesn't convince me, I'll spend some money in Watsonville, if I can convince them to let me hang the fire arm as a ballistic pendulum or clamp it to a wheeled platform.

bc, who notes JS's argument suggests rocket engineers prefer denser fuels (w/ the same specific energy), and wonders when JD will enter.

p.s. he also thinks JS has confused JC for bc.

Although not really germane to the question, I think they have the protocol wrong. Both military and civilian firing squads had one rifle loaded with a blank and the rest with live bullets. A single shot is considerably less likely to result in death than 5 (or 11).
Are we getting gruesome, or what?

I watched a TV movie last night of the CSI variety, which revolved
around twelve jurors, dismayed by a torturer/killer going
free, who conspired to train themselves to execute (!) a firing squad.
This program emanated from a country which does not
(publically) endorse state-sponsored torture, so there
was a dramatic element.

A policeman casually mentioned, the shooters would know which of
the twelve had the live round in the rifle - the recoil of course.

So here's the point that puzzled me: supposing that each round had
the same propellant charge, what would be the magnitude of the
recoil/difference?

I expect that it would be reasonable to have some numbers,
so let me pull these out of the air:
bullet: 0.030 kg
muzzle velocity: 500 m/s
