Especially softer alloy, but even COWW alloy boolits are prone to damage if roughly handled in storage or if dropped even a short distance onto a hard floor. I use fairly soft alloy for my pistol boolits, in the rage of 10 to 12 hardness for plinking and even softer for hollow point rounds. Drop any of these on a concrete floor and you have a distinct flat spot; and, like a jellied slice of bread always landing jelly down, these oops seem to hit on the edge of the bases. Then comes a good coating of PC. Dropped rounds that hit on the side or close to flat on the base are undamaged. Even one that hits the edge of its flat base will often be unscathed. Remarkable, this tough and hard stuff.
