[QUOTE="IllinoisBurt, post: 2862585, member: 35752"] The Speer product guide lists the Impact as a molecular bonded (ie plated) bullet. They use this same process for the Fusion and Gold Dot bullets. This is different from the HotCor which is molten lead injected into a drawn jacket with flux before final die forming. Traditional cup/core bullets are lead wire pushed into a partially drawn jacket with lube, then formed in dies to the final product. The plating bullets generally don't shed their jacket material, where the cup/core usually need something added to them (cannelure, discs, etc.) to keep them mechanically together. The Impact literature seems to indicate it's basically a Fusion with a polymer tip to increase ballistic coefficient and help with mushrooming at reduced velocity downrange. If the bullet stays together well that would be a nice change from their traditional boat tail bullets which have a habit of rapid unpeeling at short range. [/QUOTE]
