Weren't the M113's designed to be proof against artillery shrapnel and small arms (up to about .30 calibre), nothing bigger?
Yes. The trade off was less protection vs high mobility to arrive on the objective. The M113 hull isn't proof against a .50 cal/12.7 projectile, and I wouldn't want to take on a 7.62 AP round at close range unless it was frontal with the engine mass to help.
