Not the solution your looking for either but Nosler is now making a 7mm 168 gr Custom Competition (G1 BC of .520, is OK), but they are also making three 7mm Long Range Accubonds, a 150 gr (G1 .611 G7 .308) a 168 Gr (G1 .652 G7 .353) and a 175 gr for the big 7mm's (G1 .672 G7 .364)
Might be something to look into....
