gulli, there's always a limit to everything, but a 76 will survive undamaged a landing that causes the inertia reels to lock and the ELT to begin transmitting.
My longer stroke oleo comment was merely reference to the dissipation of energy, have recently been reading of the taming of a carrier based aircraft and its propensity to bounce on landing causing grave issues. Alteration of shock strut air pressure, metering valve, stroke and tyre pressure all get a mention.
