[QUOTE="Darryle, post: 2962173, member: 109917"] This is solid advice, JP with the HP bolt to reduce any cratering of primers and early pressure. I have a Fail Zero in one M5E1 and a Skeltonized Fail Zero in another M5E1, the Skeltonized version was very finicky to tune, the full mass was a breeze. Avoid any of the twin ejector HP (Toolcraft) bolts, they produce early pressure signs and are hard on brass. [/QUOTE]
