I shot all of my trophies on my 1st trip to Namibia with my Winchester model 70 Super Grade in 30-06. Hartmans Mountain Zebra, Kudu, Gemsbok, Red Hartebeest, and Warthog. Each required just one shot but I paid the insurance on a couple of them. I was shooting 180 grain Barnes TSX. Next time I use the 06 on plains game, I’m thinking about shooting Sierra 180 grain Pro-Hunter round nose. Anyone have any experience or opinion on these?
