[QUOTE="jcpython357, post: 28036, member: 1187"] The October issue of Shooting Times tested all the 180gr. bullets, I forget what they were using for the test medium, but at any rate they shot them at the test material at two different velocities, 2700fps and 3000fps, one for 30-06 velocities and the other 300Mag velocities, I especially noted the weight retention for the SST, Ballistic Tip and the Scirocco, they were all about the same as far as weight retention, about 84%, the Scirocco was 86%, this was for the 2700fps test, 3000fps test was about 10% less weight retention if I remember correctly, not really a huge difference considering how much they want for that bullet. I've done tests on Partitions using 160gr 7mm driven at over 2700fps, a little hot, yes, and they retained 60% both times, they penetrated 3/16" piece of plexiglas, (To simulate bone) about 3" of dry newspaper, and 3 water-filled milkjugs, shot some 162BTSP Hornadys for comparison, one bullet lost it's core, and the other was just hanging on for dear life, but they penetrated almost as far.
