Ejecta?


Dear Technoid,

Hey, what the heck is ejecta velocity?

Thanks,
Rich

Rich,

“Ejecta velocity” is a two dollar phrase for muzzle velocity of the shot load as used in the formula for free recoil. The only difference is that “ejecta” means everything that comes out of the muzzle- wad and shot- not just shot. In the formula for free recoil, the weight of everything that comes out of the barrel contributes to recoil, so it has to be factored in. Thus ejecta includes shot, wad and actually the weight of the powder charge also. The powder turns into gas and the gas goes out the barrel. The gas does weigh something, so it has to be added in along with wad and shot.

I use the phrase to confuse readers who know more than I do. By defining the rules and using strange words, I always get to win. I don’t know any more than most of my readers do, so I have to use smoke and mirrors to give the impression of Technoidal invincibility.

Best regards,
