Is there a reliable report of a bolt action .223 being blown up by a 5.56 round ?

[FatCatsDad]

Has anybody seen an actual documented report of a catastrophic failure due to shooting 5.56 in a .223 bolt action rifle ?

Is this just a highly questionable legend ?

SAMMI, throat dimension, math, engineering etc, but I cant find an actual documented failure
