No need to BT with this app – Ballistics Review

I have two Swarovski 2.6x15x56 with BRH reticles. One for my 300 win mag barrel and the other for my 270 win barrel for my Blaser. No need for a BT with this app, it is spot on out to 740 and I can hit 425 all day long. Last weekend I was on the range and switched barrels from 300 win mag to a 270 win. After zeroing at 100 I entered the bullet information into the app and was consistent at 300 and 500.
