[QUOTE="Bob Wright, post: 1518356, member: 104363"] My experience in aerospace makes me wonder why after all these years aero heating is just being "discovered" by bullet manufacturers. Bullets are technically rocket science and they have ballisticians/aero folks on staff. So, it leaves me thinking: 1.Time of flight to target made them ignore heating in all the years/decades before: (before the long range era we enjoy today) 2. Sharp plastic tips are less drag but add item 1. above to the equation again 3. They are a marketing gimmick (partially), I shoot tipped bullets....sharp tips vs smashed Spitzer points are marginally better 4. Hornady did engineer the heat resistant plastic tip and is marketing heavily, but they had to have known aero heating existed and never delved into it until they needed to bring a new design to us. It's got us all talking huh? 5. It's a non-issue on hollow point designs (SMK's, Berger, etc.....) 6. We'll continue to see other designs like Peregrine which have a interesting brass tip and copper monolithic bullet behind. It's marketing and improvement, but WE decide at time of purchase and in the field which ones we continue to load. It's disingenuous to claim "it" is just now discovered, of aero heating and it's effects on plastic tips. Their engineers really are being thrown under the bus on that statement by marketing. They took one for the team..... My 2 cents... [/QUOTE]
