E-Tip...... Anyone?

Does anyone have any experience here with the Nosler E-Tip?

I read the thread back in March of '09, wanted to see if there was an update.

I am having an issues with an elongated throat (insert joke here) and since this round has a very long base->ogive it just might work (Click Here for more info on throat prob.). I have read that it is a great hunting round especially being an all copper bullet with great expansion. But I still can't find any other info on it, I.E. BC, ext.

Thanks in advance
