I shoot bullets with the plastic tips all of the time, have never had one come apart on me.
My .243 shoots the 58 grain Hornady V-Max at quite a clip, with no problems. - Much faster than any .223.
May have just been one of those things, a fluke.
Unless it happens again, I wouldn't worry about it.
Kind Regards, Salvo
