[QUOTE="Petey308, post: 2633271, member: 106845"] Yes, they are very good with their marketing 😂. And yes, they got rid of the cannelure (which does do it’s own work in helping to adhere the jacket to the core) to cut down on parasitic drag and help boost the BC a bit more (hence Extreme Low Drag”. So in doing so, they moved the interlock ring up more where the cannelure was to still help prevent jacket separation below the ogive section. They worked together before, but if the interlock ring were to have been left low without the cannelure, you’d still potentially run into issues with core separation with high impact velocity shots. Thinner jackets, like with the ELDM, means wider cores. So the thinner metal, especially in longer, heavier, higher section density versions, tends to still conform well to the core from the forces put upon it during penetration and helps prevent the cores from completely separating. The thicker jackets don’t always squeeze down as well and can release the core without a way to help grip it in place, hence the interlock rings. Here’s an example of a 208gr ELDM that mushroomed quite well and did not shed the jacket: [ATTACH type="full" alt="49B7FFDC-3D8C-4003-ABE4-ED55A7E6E86D.jpeg"]399024[/ATTACH] Either way, good points to bring up and talk about. Thanks. [/QUOTE]
