Without finding a box of ammo and actually inspecting the rounds, is there a way to know if the bullets in any particular brand/bullet combo are cannelured? Ammo manufacturer websites rarely let you know. Thanks, C. |

There is no hard rule. Here's an example: I bought a couple of boxes of Hornady 68gr JHP loaded ammunition at a gunshow and was surprised to find the bullets with cannelures. Usually, match bullets do not have cannelures. I emailed the guy who loaded them, and he replied, saying that Hornady would cannelure their bullets if you order huge quantities for your business. He orders them with cannelures since a lot of people shoot these in AR15's. |

Good morning Cow, It's not just assuring funtioning. As I understand it, it can also assist in bullet break-up upon yaw within the target. The cannelure can reduce the structural integrity and make it easier for fragmentation to occur. That's why I do it. Most die crimping functions need not have a cannelure. I want to make sure my bullets fragment as much as possible. Big Al |

Quoted: I'm assuming there's general consensus that in an autoloading 5.56, cannelured bullets are a must? Or is it more of people just taking an extra measure of safety when normal bullets would likely work just fine? First of all, no, crimping in cannalures are not necessary. Recoil is light with this round, and bullet setback won't happen unless you are particularly rough on your ammo. Secondly, yes, it is a good idea to crimp your ammo in cannalures under certain circumstances, and for some types of ammo. Normal bullets work just fine, however it is possible that the expander ball in a sizing die could be a little large, thus preventing the proper neck tension on a loaded round. Crimping prevents this. |

GSSP, It may sound stupid but I followed your instructions by copying the link you provided and pasting it but this is the only thing I got with the picture of the tool on the upper right hand side of the unique page : Quote 'Solid Steel' Cannelure Tool This popular tool will roll a cannelure groove on any jacketed bullet from 17 to 45 caliber. Completely adjustable for depth and height. One setting will produce thousands of bullets. Also useful for making a second cannelure to lock the core to the jacket to control expansion of hunting bullets. Precision machined throughout. The cutting wheel is hardened to 59C Rockwell, so it will never wear out! Order No. 12000: $ 56.93 Unquote Does any one else see the unique page or is it something to do with my explorer? Thanx. |
