[QUOTE="Fiftydriver, post: 858051, member: 10"] Did you do any hydro expansion testing with that bullet at that speed at ranges unside 300 yards. As mentioned, on soft impacts, never saw much of a problem. On hard impacts in that velocity range, I saw ruptured partitions about 50% of the time. I did find that the smaller partitions held up to velocity a bit better then larger diameter partitions, but bullets of similar sectional density had similar results on impact and failure % which makes sense. If you look at a 140 gr 6.5mm partition, there is a higher % of guilding metal compared to lead core. IF you look at a 338 cal partition, much more lead involved. Push a 6.5mm partition to 3150 fps compared to a 338 cal partition to 3150 fps and the smaller caliber will have a higher chance of surviving impact with partition intact. [/QUOTE]
