So, let me see if I've got this straight: Immediately following my post about how misuse of terminology causes confusion and miscommunication in discussions like this, and that speaking in terms of caliber is essentially meaningless in this context you proceed to speak in terms of caliber, misusing it as a synonym for bullet weight...and now you're complaining because someone took you to mean what you actually said vs what you now claim you really meant, and then they had the audacity to post (not "shoved at" you) a formula about mass and velocity. Does that about sum it up?
