I have been studying ballistics for 20 years, and this still baffles me. Why would anybody chose a lower bc bullet at medium range.yds for example. What advantage is there in a 450bc bullet at 300 yds, over a 500 bc bullet. If you have enough twist to stabalize the 500, or 600 bc bullet, then why even bother shooting a lower BC bullet. Any high bc bullet should be asleep IE stable by the time it gets to 300 yards.
