[QUOTE="Pdvdh, post: 965694, member: 4191"] If your ballistics program matched one day, it should match again on another day under similar environmental conditions/air density, even if your BC or MV is incorrect. If your BC and/or MV is errant, then a substantial change in air density could yield differing results with the different air density. There's really no way anyone could know what's up, based on the limited information available to us. There many things that could be in play, including operator error with the ballistics program or scope turret. It sounds like you completed your first long range drop session with that load, and the second time out, you had different drops. I'd shoot it a few more times, in windless conditions. I'd tend to trust Berger's BC value and tweak the MV, unless you've got a rock solid chronograph. [/QUOTE]
