[QUOTE="jwp475, post: 447147, member: 3776"] The higher SD bullet does not always out penetrate a lower SD bullet of the same material and construction. Meplat and nose profile have a large bearing on penetration. Example solids made from the same material but with different nose shapes and profile. A 450 grain flat point mono metal solid in 458 caliber Will out penetrate a round nose 500 grain solid even at the same velocity. The flat point will shoulder stabilize and penetrate without the yaw and tumbling of the round nose. This thread is about conducting penetration test [url=http://forums.accuratereloading.com/eve/forums/a/tpc/f/4711043/m/2861098911/p/1]Terminal Bullet Performance - Topic Powered by Social Strata[/url] The thread is up to 112 pages at this point and in one test 2 bullet made from the same material and shape, but one at 435 grains and the other at 360 fired at basically the same velocity penetrated the same, not once but multiple times More to penetration than simply SD [/QUOTE]
