I can second what Bryan said about this place. Excellent animals. I killed a great looking stag, blackbuck and also a water buffalo while I was there. And I used a 300 Win Mag I had never shot for the buffalo with my guide using a 3006 for the "stopping rifle"!!! I thought I was going to get those 2 375s he had left over but no dice. And the potential was there after the first shot for things to go south pretty fast. Here is a little write up from another page my thoughts on their hardware.
Rifles
It’s a pain importing firearms to Argentina so I was advised to use the camp rifles. There were 11 hunters in camp so there was a plethora of options. Most were 7mm Mag, 308, 3006, 300 Win Mag to a couple of 375s for the buffalo. I chose a 3006 made by Midland Gun Company in England with a 6X Meopta scope. We shot at 75 meters while a guy stood off to the side and would point where we hit the target. One shot each. I also watched a guide spraying WD40 all over the bolt of one. The first day was a deluge of epic proportions. I hunted that morning in the thunder and lightning long enough to get soaked from underwear on down. Of course my rifle was also getting wet. I asked my guide what to do with it when we finally gave up and he said just leave it in his truck. (As best we could communicate, his broken English vs my almost nonexistent Spanish). That afternoon I broke out my collapsible cleaning rod and some patches. I was just trying to dry the bore as I could see the rifle rusting before my eyes. What came out looked like combination of burnt powder and used motor oil baked inside at 350 for three hours. Sludge. That evening it was 100% humidity with 1000s of mosquitoes. My blackbuck was 70 meters away. The ammo was 180 gr Winchester Silvertips. Perfect shot, he took a bullet where I aimed. At least I got the bore dry. Shot number three the next day was the red stag. It was 200 meters. Likewise he was hit exactly where I aimed. And was down in a couple of steps. So 2/2. I didn’t like the lack of maintenance but I can’t complain about performance. Bryan was hunting buffalo before me. We were told there was no 375 ammo but the next day they found 5 rounds of unknown weight. He shot twice and finished it with the 300 Win that the guide was carrying. These are huge animals. Around 2500 lbs. They aren’t as mean as a Cape buff but do have the potential to be dangerous. After he got his buffalo that morning I thought I might get the 375 with two rounds left. After all I only need one, right? But they brought me the same BRNO 300 Win Mag I had carried that morning. My guide has my 3006 as the backup stopping rifle. Anyway, after crawling for over 100 yards on hands and knees and then waiting for around 45 minutes he motioned me to take the biggest one. This was not easy with the herd of 40 mixing around but he was in front slightly quartering. It was around 100 meters and I was concerned about penetration with what I believe to be a Core Lokt bullet. Not to mention I had never shot this gun. At the shot, they all lumbered off and we followed. We found him standing obviously sick. I put three more in him but was having an hard time seeing him through the 6X fixed power Swarovski scope. Even the guide shot him once with the ‘06. The sun was low in the sky and the glare was blinding. This was not the best setup for such a big dark animal in heavy brush. This place is an excellent hunt, the animals are huge, the food is excellent, but I wish they would pay more attention to their gear.
