[meteorite-list] Iron impactors?

[E.P. Grondine]

Hi all - 

Let's look at the list:
Sikote Aliin
Whitecourt
Brenham (yeah, pallasite, I know) 
Campo de Cielo
Barringer Crater
Odessa

Now through my stroke damaged brain I seem to recall that irons compose a small percentage of meteorites, I am wondering, was an iron parent body disrupted, leading to large iron impacts?
