[QUOTE="AaronSkipDavidson, post: 1135815, member: 6373"] The Handloader-Sciuchetti Study This study of bullet penetration was documented in the June 1998 issue of Handloader magazine (Gary Sciuchetti, "The Best Hunting Bullet", No. 193, pp. 40 - 44). The author conducted an exhaustive and apparently well considered analysis of .308 caliber 180 grain bullets. In order to examine trends in the Sciuchetti data, the penetration test results are plotted for most common bullet brands and designs. These are arranged in four classes: • Commercial brands are the Federal, Remington and Winchester soft point lead-core, gilding-metal jacketed bullets; • Conventional bullets are a larger set comprised of simple gilding-metal jacketed, lead-core design offered by the reloading suppliers Hornady, Sierra and Speer, as well as the major ammunition makers; • Premium bullets are the major brand controlled expansion designs without bonded cores, such as the Barnes X, Speer Grand Slam, Nosler Partition and Winchester Fail-Safe; • Custom bonded bullets are heavy-jacketed, lead-core controlled expansion designs by custom manufacturers that all feature a lead core bonded to the jacket. The conclusion that I draw from this study that is relevant to long range hunting, is that as you dip below 2000 fps impact velocity, the chances of errant bullet performance begin to increase. The data clearly shows how one person can report good success, while another reports a lost animal. Because we can, we have the highest ethical responsibility to play above the margin. Our cartridges can be ranked for effective terminal performance by analyzing the downrange velocity. The real question for this forum is where a hollow point boat tail bullet design would rank if tested in a similar fashion. I remember reading Elmer Keith describe his testing with long range bullet performance, and he usually had to modify those old closed tipped bullets to get reliable expansion. I predict that the ability to design a bullet for ultra-consistent terminal performance at low impact velocities combined with consistent and low drag will push a company to dominance for our long range hunting niche market.
