One is thousands of an inch, which is a typical unit of measure for milling operations. As the other person in this chain has said, ballistics is a weird game. End of the day, m(ass)*v(elocity)=f(orce), and the goal is getting f to a useful value. At that level, big and slow and small and fast have the same outcome. But, because ballistics is bastard, other factors start to interfere.
For example, If you want to shoot farther, you can either go faster, or be lighter. Going faster requires more powder in the case, which creates a different profile for the round and changes the acceleration profile during firing (there are several rifle rounds over the years that have approximately the same load and bullet, but are ever so slightly different shaped, to change how the powder burns off and how it accelerates down the barrel)
Being lighter reduces your final impact force, and can impact stability mid flight (leading to alterations to the length and profile of the round itself)
Closer to the first point and tangentially related, the US has been a capitalist hellscape for a while, and has numerous instances of a company making a firearm using a new round because they did the math and said this is what we want and what you should want, followed by everyone else making more or less a clone of it if the gun in question sells well. Due to copyright it can’t be identical, but as math goes, there a lots of ways to reach the same outcome.
To be fair That’s the headquarters. Actual manufacturing sites are completely unharmed by this. All they’ve done is damage some show models in the atrium of the headquarters and maybe spooked some suits.
If you want to make a difference, honestly crippling cloud service facilities and directly targeting Microsoft server farms is a better bet. No idea which one, so targeting fanuc data directly isn’t easy, but even crippling teams and outlook stopped work for a day when a storm knocked out power to Microsoft site in Colorado that. Pretty sure it was a mass reported issue, so not just my corporation impacted.
Or, if you wanna hit a manufacturing site, some maps snooping (our various other sites aren’t a secret. What they all do isn’t public knowledge but their existence isn’t) or poke about the offices at headquarters. Know how many processes maps and diagrams around our local plant have suppliers and sub assembly process sites for easy explanation to managers?
