[QUOTE="Mikecr, post: 591604, member: 1521"] How does this make sense? I know plastic tip bullets are stable beyond predicted, but I don't understand why. It would seem to me that lighter plastic tip -for a given weight and length of bullet, would move center of gravity backward,, reducing stability. I might think that the smaller meplat of the tip could move the center of pressure backward, apparently even moreso than center of gravity moved backward. BUT, BC of plastic tipped bullets is no better to worse than typical HP LR bullets. So this Cp notion is not supported with that, because if I form a non-tipped meplat smaller, both BC and stability go up.. What am I missin? [/QUOTE]
