[QUOTE="Pdvdh, post: 1362418, member: 4191"] Try to confirm you have an accurate BC value before proceeding. Otherwise both BC and MV will be unkown and you'll be chasing your tail. One purpose of an accurate, established, measured MV is to eliminate that unknown. And to not have to estimate MV by bullet drops under all the sources of additional error affecting long range bullet impacts on distant targets. Which can include wind error, BC value error, scope turret value error, light refraction error, shooter caused error, etc. [/QUOTE]
