I checked the balistics with the winchester site and applied it te JBM calculations page and came up with the follwing: 150 xp3 is bc of .444 and the 180 xp3 has a bc of .536. This isn't perfect because I don't know the altitude of temp that the win site testing was done on. but it should be very close.
