[QUOTE="Its204fast, post: 1977030, member: 114347"] I'm not a physicist. Regarding transonic destabilization of a bullet, it would probably help to look at what a jet endures making the transition from sub sonic to super sonic and back, however, the jet has propulsion so I would expect some differences there. the APS rifle was designed to fire under water but there was different "ammo" for it, which was 5.66x120MM and only had a very short range somewhere around 100yds I believe. I would think the length of the proj was what contributed to it traveling as far as it did. where most bullets tumble the second it leaves the barrel in water. I feel certain (relating to ELD bullets) this is the trick for bullets passing from super to sub sonic and not destabilizing. [/QUOTE]
