Well, I have sheared lugs on three Colt 7.62 X 39 bolts in a Grendel, one AA Grendel bolt, and a machined out 5.56 bolt. I have also sheared a lug on a Grendel bolt in a 6 AR.
However -- these bolts were before the enhanced bolts that seem to be holding up well today. Before these enhanced bolts, there were periodic reports on the forum of guys shearing lugs. It was not uncommon and seemed to plague the Grendel until adjustable gas blocks and the enhanced bolts.
