SA East Cape: Kudu Min Legal caliber??

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.

Hi Divernhunter
I am guiding 20 years in SA and i have not seen or read anything regarding the .30 as min caliber for kudu, my son also a guide just return with clients from my area in the eastern Cape and one client was shooting a 270 he got himself a very good kudu. I had seen a number of animals going down with a .260. As long as she can shoot it well she can hunt with it. At the end of the day it is all about bullet placement.
Enjoy the hunt.

Divernhunter I know of no law in South Africa that says you must use .30 or larger for Kudu, while I was there this year every PH I talked to recommended the 270 for everything up to Eland. What I would suggest is that you contact the outfitter that the two of you will be hunting with and see if they have a min. requirement if not then I say let her go for it. just a note the difference between the 25-06 and the 257 Roberts isn't enough to get concerned about you may want to think about leaving the 25-06 at home and take her 257 Roberts and make her day.

Basically it used to be 6.5mm min caliber, they are now going with bullet weight instead of diameter, see dimondhitches reply.
Personally I prefer 7mm and up for kudu, but that is just personal preference.
