run the tests and shoot them, you'll see, published BC isn't very often what you'll actualy see.
I shoot alot of 160 accubonds published BC of .531, the only way to get my charts to match my actual shooting is to use .62 as a BC, same as the .264 berger 140's, published BC of .64, my charts match my trajectory out to 1060 yards using a BC of .7.
The only bullet I ever shot at long range that matched my trajectory using the published BC was a Lapua 139 gr scenar, and it sux for a hunting bullet.
