On Sango, the buffalo hunting is good. I've shot four bulls on the Save, all in the 40 inch class. All were very solid and old and big bodied as well. You will have several opportunities at mature buffalo in 10 days and you should get your bull if you can walk, see, and shoot. Provided, you will not see herd of 100s of buffalo every day. You will track groups of 6 to 10 dagga boys and the occasional herd of 40 to 60. Very rarely do you see 100 buffalo, but it does happen.
I'd say the best option for buffalo with your wife along would be out of the Sango lodge. However, you could also make a nice hunt from Hammond - ARDA, which is also run by ZH. In fact, we really enjoy Hammond camp and Hammond - ARDA are, in my opinion, the best buffalo areas in the conservancy.
Hello Milan, I just watched your video on disassembling/reassembling the CZ 550. I have spent days looking for something like this. I now have no reservations taking apart my rifle. I like to do this with all my guns so I understand them "inside and out". Thank you very much for the information. It is greatly appreciated.
