"The Ruger company did a comparative test with their M77 action against a Mauser, they tested the strength of the locking lugs on a Olsen tensile machine and the Mauser lugs sheared off at roughly 29,000 pounds compared to 40,000 pounds for the Ruger. If we look at Daniel Lilja's formula above, applied to a Mauser action made from 1040 steel, we find that it is basically spot on 14,263 x 2 = 28,526 pounds. Based on this empirical test and calculations, I feel that the Mauser locking lugs are strong enough. I consulted with other gunmakers and they assured me that they have never seen the lugs breaking off, save for one gunsmith that said he had seen one bolt with a cracked locking lug."
