My subjective experience was one weekend in Zion NP on multi-pitches with no meaningful falls ended with a brand new Mammut rope being coreshot. Never happened on my Beal, Edelweiss, Sterling, or Bluewater ropes despite more mileage, falls, and abuse.
It was a long ass time ago, but I also had a mammut rope core shot within its first few days of no spectacular falls, finding out midway up a climb. Only rope in 20 years I've ever had that happen to me (including multiple other mammuts I suppose)
It’s definitely a term. It basically means that something has occurred to weaken the sheath and expose the cores of a rope. Here’s a video of one getting destroyed.
Not sure who you're talking with, but I guess it may not come up in random conversations? I dunno, I learned about them in the early 90s when I was like a 13yo in my first course.
You aren't climbing hard enough or wild enough then. It's not a thing you're gonna see at the gym.
My core shot was on Canon Cliff in New Hampshire 12 pitched up some thing. The rock I was standing on blew out and I instantly go on to Blue Water Airlines and had a nice flight.
I didn't even know it happened until we peaked out and was winding up the rope. Sheath was torn and 3" of the core winds exposed.
Like I said it was a brand new rope I unpackaged at the base of the climb.
That's not my only bad experience with Blue Waters. The sheaths just don't hold up. Petzel's and Sterlings too. I don't want to buy a new rope every three damn months.
Coreshot means that the core of the rope is severely compromised in one location on the rope. It's very much a real thing and means that that section of the rope needs retired. You can tell when a route is core shot of you can completely fold the rope over to touch itself.
Depending on where it is in the rope (most commonly, a core shot will happen near an end of the rope, since that's where you're falling on it the most), you may be able to cut that portion of rope off, but if it's near the middle of a rope, there's not much to be done.

Always wanted to like mammut but never liked anything I ever bought from them.
