old style Hornady Interlock ballistic coefficient?

[legi0n]

do you guys happen to have handy the ballistic coefficient of the old style (tangent ogive) Hornady Interlock, 30 cal, 180 gr? (SP, FB)
the recent ones have a secant ogive.

If you are looking for info on the #3070 bullet, according to the 3rd edition Hornady reloading manual, they claim .431 for a BC.
