Here's one I actually did take with the .458 Teck. This was in Kenya in 1971, up near the Tana River. The old guy had recently broken off the other tusk and the nerve was still festering. The one remaining weighed in at 94 pounds. Had the nerve not been so large, it would have gone over 100. He was on his last set of teeth and they were so worn down he would not have lasted much longer at any rate.

This one was taken in the Selous in 1972. The ivory was long and relatively thin: ran about 75 pounds to the side, which is pretty good for the area. I climbed up on top of a termite mound to shoot this one, since I didn't have a ladder handy. One shot behind the ear did the job.
