Glad you had such great success. That is a whopper. Was it quartering towards you? Did you have much of a tracking job?
I was walking the road slipping up on water holes and marshy areas with a shooting tripod opened up and ready in my right hand and my rifle in my left hand. I turned the corner on one area and the Sambar came out from under a tree really close to me, maybe 30 yards, and started to run angled away from me. Not a fast run, but fast enough.
I planted the tripod, put the rifle on it, followed through and shot. Being off a standing rifle rest I thought for sure I had hit it good, but the Sambar kept going and turned a corner in the opening and out of my sight. I grabbed the rifle and ran to the corner and found the Sambar had turned broadside to me but still running and picking up speed. I lined up best I could as fast as I could and shot. Like before it did not react at the moment of the shot, but a few yards later it stopped running and fell over. I was confused as to where what bullet went where at first as one side had a rear and a forward gut shot hole and the other side only had one gut shot hole, yet I found lots of rib pieces and a blown lung while field dressing. While skinning and cutting it up I figured out that the first bullet was an angled through body shot hitting mid body on one side then deflecting at the ribs on the other side going forward through several ribs rear to forward bringing stomach contents with it through the broken ribs and under the skin almost to the shoulder blade. The bullet did not exit! The second shot was a broadside gut shot and went all the way through. Not where I was aiming of course, but with me running in that swamp grass and it running I was lucky that my second shot even connected. I was shooting a Remington 700 in 300 Weatherby with 180 grain oryx bonded. Very tough animals.
