I operate HuntsNTa safari hunting business in Australia's Northern Territory. A couple of years ago I stumbled across Mike Brady's North Fork web site and immediately understood Mike's performance objectives for his bullets. We did a lot of emailing and eventually I purchased 2 boxes of 416 370SS for my 416 Rem Mag. I can say that the performance on big buff which are reputadley tougher than Cape buff has been outstanding. With a 3.64 magazine I crimp into the second groove and with a of load 83 grains of RE15 there are no signs of pressure. I don't bother with velocities as it's what happens in the field that counts and this load literally blows big buff off their feet over the shorter distances. The NF bullet is also dynamite on scrub bulls or feral cattle which are sometimes big Brahman X breeds. Unfortunately when I heard NF had gone out of business (not any longer;)) I removed a reference to North Fork from my web site. I intend rewritng info on the virtues of NF bullets which are the best we have ever used and that includes Barnes and Woodleigh. The cup head solid also makes a lot of sense as in many situations normal solids just go on through without any real damage or stopping effect. North Fork a truly innovative bullet company.
