[QUOTE="Gcan, post: 1821397, member: 102867"] the issue needs to be rephrased. The issue is not equal thrust of this or that. Yes. Thrust is thrust pretty much. The issue arises with a case that can create enough rearward thrust to overcome the structural integrity of the lug abutments before the case shows pressure signs. The LM’s bigger case head and thicker case base allows the same pressure to be spread over a larger area thus reducing the per sq inch forces. This creates the same pressure over a broader area allowing the fullest transmission of force to the bolt with the least deformity Of the case. [/QUOTE]
