Again in Zim last September.
Shot @ about 60m or so - we were closeish, call it 100m+, maybe 150m and hopped out of the Landy. The PH said: "Follow me low, this is going to be quick!"
And off we went in a quick crouch. At about 50-60m we stopped, he quickly pointed out the stallion and just as they took off, he whistled, they stopped, I fired!
Perfect shot (again, a-hem). .30-06, 180grs Speer Grand Slam. The stallion run less than 100m.
The PH and tracker had a dandy time mimicking the stallion's reaction at the hit. He was mighty pleased with the good hit (the PH, that is; not so much the stallion...)
