Over here in Edinburgh, Edinburgh Rifles imports the Fox Bullets and the South African Peregrine bullets. I know them well and done some load development as they load factory ammunition with both these bullet ranges. These have been sent to proof house and are now being supplied in good volumes major government, and conservation agencies as well private estates and retail.

The Fox works well and has multiple groves cut into it, so does keep pressures low. The Peregrine is built slight sub calibre bullet with driving bands to grip the rifling. And they have a range - the VRG3 designed for dangerous game calibres.

Personally I would be happy shooting Fox bullets out of an old rifle, but I would prefer to use the Peregrines.

More details, and load data etc available here with links back to manufacturers websites.
