Mike I think Argentina is about the cheapest buff hunt generally available. But personally I would really want to know how it will go, not that they take you into a cow Yard to shoot one. I do understand they can be great hunts. But it will likely a subspecies with smaller horns than the Australian variety.
I recently emailed them about gun rentals for Buff and he had a pretty good story about a client aiming to high and the trucks getting rammed while they went looking. So it should be good fun, but I will make sure to get a bit more detail before we run off to do it. I don't want to shoot from a truck or just pick one out of a field without a hunt. I watched a video for an online hunting series for buff with this outfitter (TGB) and it was a 'spend 4-5 days chasing them through the woods' kind of hunt, at least it seemed like it was. I plan to hunt the stag as you did - free range, chase the roar. Thanks for the advise!
Congrats on your two stags! That picture looks like a really nice stag.
