All the Weatherby ammo includeing DG capable stuff, was available 4 years ago at the Powder Keg in Jo'Burg, plus some euro cals from Euro manufacturers eg Blaser 9.3x62 ammo.

One shop in Bloomfontein had all the common PG calibres.

Cape Town had very little. I suppose for some calibres you have to ask for what is not on display ?
