    On the JLk website they show a 6mm 105 gr VLD with a BC of .560. Has anyone tested this bullet to verify the BC or has come up with a different BC for this bullet as a result of testing?
    Thanks, Bill.

    Testing BC is beyond the ability of most mortals, you pretty much have to take the manufacturers word for it. Berger started the g1 and g7 figures, and I still don't understand the difference between them. I simply use g7 figures.

    ZSteinle - Thanks for the info on the G1 and G7 BCs. Could you provide a little info on how you arrived at these figures. For example is this data the result of shooting the bullets at longer yardages or from something that you read?
    Thanks, Bill.
