[QUOTE="Pdvdh, post: 2587264, member: 4191"] I hear you, but still see no need to adjust MV in addition to BC. Seems like you're adding a second, unnecessary fudge factor. The purpose of BC value in a ballistics program is to accurately predict downrange bullet velocity over distance, which then enables the software program to predict accurate elevation and windage dope. Shouldn't have to enter inaccurate MVs into a ballistics program in order to get accurate predicted downrange bullet velocity. The proper BC value accomplishes that. I input my known LabRadar MV and an "average" BC value that correctly predicts bullet POIs at say...., 1,000 yds. Or as far as I can set up, shoot, and measure bullet drop on my target backer. I understand the BC value of the bullet in flight does deviate slightly across that 1000yds as bullet velocity decreases. But the slight differences in BC value from the "average" value I input - across that 1,000 yd distance of bullet flight - doesn't cause enough error in predicted bullet velocity and flight to cause non-lethal hits on large game when dialing elevation dope at closer yardages.
