30 CAL 180GR coefficient data help

[338 LEGEND]

Does any one have data on the 180 gr accubond bullet for long range ( coef )? I know the starting coef is .507

I am using .524 in my 12x 300 RUM based on double chronies AND drop tests out to 725 yards.

Actually, that is the ballistic tip that I am using. The AB should be very close but possibly different.

.507 has always seemed low, not only mathematically but also in the real world.
