Headed to SA East Cape in 2013 with my daughter. I plan to take a 338Win Mag and a 25-06 shooting Swift A-Frame bullets. She plans to take her 257Roberts using 120gr Swift A-Frame bullets. She wants a Kudu. I think I read somewhere that in SA the legal min caliber for Kudu is 30cal. Can someone tell me if this is true or not?----Thanks for any help.
