[QUOTE="WildRose, post: 2403201, member: 30902"] I know this thread is old but it popped up on my page and I started reading it again. Bench rest guys for decades contended that if a bullet didn't properly "tip over" by the mid point of the flight they would gain lift erratically screwing up their groups. There at least seems at least to me some possibility that the lift principle is indeed possible with some bullet designs because they are heavier in the rear than at the front. The more streamlined the bullet the more this center of balance changes. I don't know if bullet manufacturers take this into account with respect to the cavities on cup and core bullets attempting to keep that balance point forward of the mid point to get a more level flight. From a layman's perspective at least I would think this to be more of an issue with VLD's and maybe explain some of their problems in the transonic range.' Doppler and wind tunnel testing along with modern computer modeling would certainly make exploring the possibilities easier. Be sure someone credits me for the idea when one of the Manufacturers patents it and makes a hundred million or so off of it... . I probably won't be around to spend it but I've got some heirs we could put through college with it. HA! [/QUOTE]
