The tested .591 BC is whats called a midrange or 200yd BC, most new bullets including the eld range are now publishing data from this testing to more accurately reflect the calibres they are shot from, they will usually also show a higher and lower number as a verified bc at a certain velocity. Most apps will allow you to enter all 3 numbers, the 150gr ablr I use(d) being .625 .569 and .531 which was bang on out to 900yds in my wsm
