Congrats on your hunt and shot. I just looked up at my first one on the wall and darned if yours is a bit longer horns. I shot my first Nilgai with my 1895 .405 WCF and 300 grain bullets. Here is a pic of my second on taken with .405 Simson Suhl double down near Hondo right after 5 inch rain. My son shot one that went down about 10 yards away. Enjoy the meat!
