Just recently, my Brother-in-law and I were attacked by a ferocious VW bus ( "It's comin' right for us!" ), armed with a only a .222 we managed to defend ourselves quite well.
.222 will:
Penetrate both windshield and 33% of the time the back window after going through the windshield.
Windshield, dash, front seat.
Both sides of body
Body and 1/2 steering column.
Windshield, fire extinguisher, dash.
Since the windshield was double-thick safety glass, we were unable to make it blow out like the rest of the windows. And thus had to return with 7.62x54R to shoot out the pillars.
