Yes - I am interested in the on-going situation as well.
A buckled case will certainly hinder chambering but I cannot see where it might effect extraction.
Crimping on bullets without a cannelure is not wise & usually does no good. ( buckling is the oft-result as 9.3x64 noted)

With descent bullet pull (snug seating), there is no need for crimping in bolt action rifles with vertical stacking magazines.

Crimping will not effect pressures, normally - most ALL factory ammo is NEEDLESSLY crimped, imho, except for rounds loaded in tubular magazines, like the Winchester and Marlin lever guns.
If crimping improved accuracy in normal CF rounds, bench rest & long range competition shooters would be crimping their handloads.
They don't even in excessively short necked rounds like the .300 Win. Mag.
