what is the closest bullet out there (new) to the 30-06 M2 bullet?

I'd say Sierra's 150gr FMJBT.

For a FB'd bullet the M2 bullet is pretty pointed and the BCs I've measured (Oehler M43) run between .385 and .395. The hornady 150 gr FMJBT comes the closes with and actual measured BC of .393 out of a 10" twist barrel at 2790 fps. The Nosler 150 SPT comes close as does the 150 Speer SP and Sierra's 150 SPBT.

Hornady 150 gr FMJ BT gave me the best results and a duplicate of trajectory @ 300 meters.
