[QUOTE="Brent, post: 32032, member: 99"] Just fir kicks and giggles, I changed the tip diameter for the 210 JLK from .060" to .070" diameter to compare the BC's predicted. Started out at .670 BC, down to .645 BC. I don't imagine you cut the tips back so far the diameter increased much more than .010", or if that much, so I'm guessing the BC change was air density, posibly in combination with uniforming the meplats?
