[QUOTE="RockyMtnMT, post: 1624626, member: 7999"] Too bad I'm not a rocket scientist. The way I understand the pressure it is the pressure from running above the sound barrier that causes the instability not the air. Could be wrong here but it is different than the drag of air under the sound barrier. It's the pressure wave that concentrates closer to the tip the fasterthe bullet is moving. Also it seems that the higher density the bullet material is the less It is effected by this. So far we have only tried bullets with a 1.5mm hollow point. Would be interesting to try the same bullets with no hollow point. [/QUOTE]
