MJK Safaris is hunting Chewore south in Zim this year. I was just talking to Tini Kok yesterday and he indicated they have some buffalo available in Chewore this season. MJK is Tini Kok and Lin Stanton. Both quality PH's. I have accompanied Tini on several buff hunts with great success.
PM me if you would like Tini's contact info.
