32gn SS190 AP use (From FN 5.7)

I came across these and wondered if any of you guys have used some of these bullets in a slow twist 223, 22-250, etc. I really don't see a need or an advantage to using these other than for something different, but I think I would be interested in getting a few to try out.

"Pulled .223 32 grain ss190 Black Tip Armor Piercing bullets. These were pulled from 5.7 ss190 ammunition. Before you buy these please make sure they are legal to own in your city/state. They have a steel tip insert with an aluminum core. They are light but should work well in .223/5.56 or other rifle cases."

They pop up in the auction sites from time to time and had me curious. I wouldn't expect great accuracy from pulled bullets anyway.
