light bulbWow, just looked at Hornady's website, I don't know how I got the lower BC number in my head but .290 sure makes more sense.

Thanks for pointing that out...clearly I'm an idiot:p

every bullet I ever checked shooting here has a higher actual BC than published with the exception of the lapua 139 gr scenar. I also shoot and hunt from 800-3000 ft.
the 160 accubonds I shoot alot are published at .531, to get my drops right out to 1k I use .62
