    Sirocco swift 6.5 130gr and 7mm 150 gr G7 BC

    Anyone using either of these projectiles and if so what G7 BC are you using? The manufactuer G1 BC is a little high I reckon, so it in turn, it throws out the G7.
    I have used .252 which is a Litz calculation for the 6.5 and it seems to work.
