[QUOTE="orkan, post: 2526458, member: 25377"] Perhaps a video demonstration will help. You'll notice in the video below that there is a gray puff of smoke to accompany the chunks in some of the videos. That little gray puff could be witnessed when I shot paper at 100yds. The bullet was a 17cal being spun hard in a barrel designed for 30's. The forward momentum of the energy was delivered in an instant as the bullet comes apart. Were it to stay together, the energy transfer would be happening in a much longer period of time. The same principle that allows a slow object to pierce water, but a fast moving object gets obliterated on its surface. A very pointed demonstration of this at 2:30 in the video. [MEDIA=youtube]QcPWCYS7OCU[/MEDIA] Energy transfer over time is a critical factor. Same energy delivery on a significantly shorter time, is vastly more destructive. Drastic oversimplification, but you get the idea. ----------- [URL='https://www.instagram.com/primalrights']Follow on Instagram[/URL] [URL='https://www.youtube.com/user/primalrights']Subscribe on YouTube[/URL] [URL='https://amzn.to/3txlBnp']Amazon Affiliate[/URL] [URL='http://www.primalrights.com'][IMG]http://primalrights.com/images/signatures/sig1.jpg[/IMG][/URL] [/QUOTE]
