[QUOTE="shinbone, post: 2072250, member: 15248"] When people who have been shooting lead bullets transition over to all-copper bullets, they frequently bring the "lead mindset" with them, which is "heavier is better." I know I had that thinking when I made the change to copper bullets. Lead shooters have to think this way because a lead bullet will lose a substantial percentage of its weight on impact, and thus needs "extra mass in reserve" for good penetration. However, "heavier is better" doesn't apply to copper bullets. This is because all-copper bullets lose either little-to-no mass, or, the mass they do lose is by design, and that lost mass still does tissue damage in the form of shrapnel. I.e., no mass goes to waste with a copper bullet. And, even when a copper bullet loses its front 40%, the remaining bullet shank is still going to fully penetrate. Not to mention that Hammer bullets (and other all-copper brands) frequently kill by hydrostatic shock, which, means, more bullet velocity is better. In other words, not only is a heavy copper bullet not needed, but it, is counter-productive by reducing bullet velocity. As for elk, boatloads have been killed with 130gn - 150gn lead bullets at 270 Win speeds. Drive a 137gn or 152gn Hammer Hunter at 300WSM speeds, and the elk will be dead before it hits the ground. The 124gn HH would be a real elk killer, too, and you would have a laser-like trajectory out of your 300WSM. [/QUOTE]
