| Question answered, thread degrading to teh ____. |

Quoted:
on rifle bullets as well. Can be ordered either way, depending on if you crimp or not. Where should the case meet the cannelure? Right in the middle? [Even spellcheck on Mozilla and ARFcom don't recognize the word]. It was obvious, but I don't reload. I got some factory ammo with a fully exposed cannelure and I'm surprised by how much of the hollowpoint they had to shave off/crush to get to the proper OAL. ETA: Thanks for the answers. |

Quoted:
The knurled groove in a jacketed bullet is a cannelure, for crimping. The smooth grooves in a lead bullet are for holding lube. This. A cannelure will be a narrow, very shallow groove. Lube grooves will be wider and deeper. Also, while you'll have multiple lube grooves frequently, there's only going to be one cannelure (although I want to say I heard/read about some rifle bullets that had two... not sure). |

The top groove is the crimp groove, the lower is the lube groove. Some bullets have smaller, multiple lube grooves and/or two crimping grooves.  Very few jacketed bullets have two crimp grooves, such as the Hornady .358 180 XTP or the .430 300 XTP. |
