:lol: that was when Bill A was trying to tell everyone the reason his bolt face was deeper was to make it stronger and he "engineered" it that way :lol: That fact is he was opening up 5.56 bolts and had to machine out the shadow line, then make up a good story as to why they had a deeper recess. He actually said his bolts were stronger than a 5.56 or 6.8 so strong in fact he had to impose a 52000psi limit to try to keep them from breaking.
On the Grendel site they have a "Broken bolt" club. Strange that we don't have one of those.. Dammit they have something we don't
This all brings back fond memories of week long arguments :lol:
