[QUOTE="MontanaRifleman, post: 262831, member: 11717"] Lift is caused by a pressure difference between the upper and lower surface of the "wing". The wing has a cambered shape that results in greater surface area on the upper side of the wing which results in a longer path for the air molecules to travel accross the upper surface of the wing, which in turn creates more space between the air molecules, which in turn creats a lower pressure above the wing. A bullet, tubular or otherwise, can not create lift because it doesn't have the properties of a wing. The shape is constant below and above the bullet resulting in the same flow of air all around the bullet. No pressure difference. We can all sit around and speculate, but the proof will be or not be in the pudding. Loading them up and shooting them through our barrels will show just what their BC is or isn't. I also plan on testing the .308 177 HV's in my RUM with a 10 twist. The twist is on the slow side for the bullet, but if I can achieve 3500 - 3600 fps from them I think they may work. Another attractive thing about these bullets is they can be driven at higher velocities with acceptable pressures. As in 100-200 fps faster. In the other thread, Gerard said he was currently busy testing the SP (target) line, including testing them on game. He said after he was finished with that he would look into LR hunting development.
