[QUOTE="WildRose, post: 1131955, member: 30902"] As I mentioned in another post, maybe on another thread Perigrine is using a combination Copper tip driving a brass plunger into the bullet for expansion. As for what all goes into expansion there's a whole lot of factors. Yes how deep the plunger is set and how deeply it penetrates is going to be one factor. Another is the allows used. The Sirocco for example stays together as well as any bullet I've every used but both the lead and the jacket seem to be too soft allowing for the bullet to flatten out ridiculously sometimes causing the bullet to fail to track straight through. I've seen them turn 90deg at times most recently on a wharthog and a big blue wildebeest but I've also seen it on white tails! I've recovered some of them flattened out the size of a silver dollar or even an old .50c piece! The tapered jackets like Hornady uses start off thinner at the tip and thicken to about the mid point. Hornady's interlock has been my go to bullet for a couple of decades because even though it's not the best long range bullet because of the BC I'd simply never had one fail to expand as it should. I attribute that to their metallurgy being great with both the jacket and the lead core but also their bonding process. From what I'm seeing of the design of the new ELD X I'm pretty excited because it appears they have used a combination of the interbond's bonding process along with the cannelure of the interlock, and done all of this combined with the VLD shape and the new heat shield tip. I'm really pumped to see this offering after the let down many of us had with the Nosler ABLR. [/QUOTE]
