Yellow Jacket protestor loses hand from grenade (warning, graphic!)

I believe some of these protesters have been throwing tear gas grenades back at the police but I believe this one actually had TNT in it.

That was an excellent explanation...thank you for taking the time to do it.

I kind of assumed that the relative shape and function of say, a tear gas canister, would remain largely unchanged over time, a good and simple design...In retrospect I guess that wouldn’t be true.

To make your case you have moved the goalposts from 2 to 5 grains.

Thank you for taking the bait.

I collect vintage firearms. I have several 1895 Nagant revolvers. The recipe that I use for the cartridges that I reload for them specifies 2.4 grains of Titegroup powder to achieve the same muzzle velocity as the originals. I use 90 grain projectiles in them which I cast myself.

If you were to look into the history of the Nagant revolver you would find that one of the original design requirements from Tsar Nicolas himself was that it be capable of killing a horse with one shot to the head. It was an ironic twist of fate that it was also the weapon used to slaughter the Tsar and his family following the Russian Revolution of 1917.

Approximately 2 million of them were produced from 1895 to 1945 when production ended. It was the standard Russian sidearm until the 1930s. But it was produced concurrently with the Tokarev tt-30 until the end of WWII because of production issues and the Nagant’s reputation for robust service under challenging conditions. Much forensic evidence supports the theory that it was the most commonly used handgun for executions in the Soviet Union from the revolution through WWII. Because of its unique design which makes it one of the only revolvers that can be effectively silenced, it was also one of the weapons of choice into the 1960s by the KGB to perform political assassinations.

So you can ridicule the power held in just two grains or 0.00457143 of an ounce of smokeless powder all that you want. It demonstrates only your ignorance of firearms history and the construction of firearm cartridges.

2.4 grains gives you over 1000 fps?

You are insufferable.

My step-son blew off half his hand about six months ago. I was very surprised how little blood he lost.

Looking at my notes, the gas seal style brass typically achieves 890 fps with 2.4 grains of Titegroup and a 90 grain projectile as confirmed by chronograph. If you add more powder, the projectiles typically go faster, but the object of the exercise was to come as close to original specs as possible with the exception of using modern available powders. The commercially available cartridges for this gun produce I also put together non-gas seal style cartridges that I make out of brass originally intended for 32-20 cartridges.

I will repeat for the third time, the point of my original post was not to get into extreme minutia about specific numbers, but only that tiny amounts of propellant contain a surprising and dangerous amount of power. 2 grains or 5 grains or even 30 or more grains as used in full size rifle and shotgun cartridges are all still just fractions of an ounce. 1 ounce equals 437.5 grains. Your mocking and nitpicking of this point is puzzling.

[fireman15]

The current commercially available cartridges for this gun achieve only around 690 fps as tested by me. This is probably because a typical 1895 Nagant revolver is close to one hundred years old and the people who produce the cartridges are probably nervous about getting blamed if one of them blows up in someone’s hand.
