hatari,
Looks great! I love the idea of shooting, steaks, and Mallbec!
If you are willing to name this place, I'd be interested.
More than happy to share ALL the info. Family friends lease the estancia out to an outfitter who is very well organized, speakes English 100%, and communicates better than any other outfitter I've ever dealt with. Did I mention it's dirt cheap, especially if you can use FF miles. Cartridge bill is all up to you! PM sent.
