[QUOTE="lisagrantb, post: 574001, member: 11072"] I have used Bryan's G1 bc numbers to predict bullet flight profiles for 22, 6mm, 6.5mm, 257, 308 and 338 VLD type bullets with great success. I never even had to adjust the DK value off the default .5 value, that shows how accurate the BC numbers are from Bryan. This is the first time I've tried it with the hybrid Berger bullets, but in theory it shouldn't matter if the BC is accurate. the DK method developed in part by Arthur J. Pejsa is a highly accurate way of calculating trajectory. [/QUOTE]
