100% fact.
In your delusional mind.
As a lifetime student of human behavior, I admit, I am fascinated by a mind that can conclude that because an entry wound that is measured to be “.250 cal.” made by a projectile that continues in it’s path to do severe trauma to such structures as the Petrous bone can conclude that this wound could NOT have been caused by a projectile of .223 cal. diameter but WAS caused by a projectile of 9 mm or .45 cal. at subsonic velocity.
A mind that is capable of such mental gymnastics is probably capable of amazing feats of delusion.
