so i have been following the barrel discussion and thought i would ask how to understand how to measure my grendel bolts. i understand they need to have the proper space where the shell sits to properly chamber that shell into the chamber. i have a bolt that measures from the lugs to the face at .136 and i also have a different one that measures only .128. i know i should have looked up the correct names for the parts of the bolt but carry me here. i will bet that i should have to measure from the other side of the lugs,,
