I have hunted and reloaded for many years here in the USA. I have sucessfully hunted wild boar/deer/pronghorns/bear. Loaded ammo for sucessfull elk hunts, moose hunts and some others. I am no stranger to bullets and differences in construction and application. I am going to SA for a PG hunt with my daughter. The rifles I want to take include 338Win mag,25-06,for myself, 6.5X55 for both of us and her 257Roberts. I have always had vey good results with Nosler Patrition or Swift SciroccoII or Hornady Interbond or Hornady SST bullets. After much reading from everyone I settled on Swift A-Frame bullets since the normal choices were ruled not good enough. This is my only(due to age and $$) trip I will be able to do and I want to be sure I am set up as well as I can be. My hunting shooting skills have always been fine. I am planning on taking a wart hog,Gemsbuk, impala, blesbuck, Blue Wildebeest, springbuck and we each want a Kudu. Loads under consideration all Swift A-Frame bullets all data from my daughters and my rifles over a chrono average of 5 shots. I am looking for the fastest loads which I can shoot under 1" @ 100 yards off one sandbag under the rifle front. 257Roberts - 100gr bullet @ 3016FPS 25-06--100gr bullet---3300 or 3431FPS 6.5X55---120gr bullet---2824FPS 6.5X55---140gr bullet---2677FPS 338Win Mag--225gr Bullet 2902FPS I have some loads worked up with 120gr Swift A-Frames for the 257Roberts and 25-06 I still need to test. After all that background my questions are. I have shot many animals with my other bullets with no problem. Never lost an animal yet. I sure do not want to in Africa. However after checking the size of the animals I want to hunt I wonder if maybe the Swift A-Frame bullets may be too stout and not expand for a quick kill. I had this trouble with too heavy of Nosler partitions and others on our small deer. Went to a lighter and pushed faster Nosler Partition and no more trouble. After reading just how tuff the African game is I wonder if they have Kelvar skin and armor shields under the hide. The way some talk I should load up my 50BMG rifles with 647gr Barnes X-Bullets or 700gr AP bullets at 2900FPS+ for the African game. Whats the facts? After all this work I am told that "THE" bullet to get is the North Fork Bullets and they do not make a 25cal bullet. If they are so much better I will go to them. But are they? Do I need them? I have other rifles I can use but wanted to use the above ones. Are they poor choices? If I had to I could use one of the rifles in 257Weatherby/308win/30-06/7mmRem mag/300Win mag/6mmRem(too light for me)/7mm-08 or 45-70. But I really would like to take the ones I started with or the 7mm-08. Just how much tougher are the African animals I have choosen? Any suggestions as to cartridges and especially bullet selection. I am reluctant to use the Barnes bullets because of the way they screwed us here in Calif,USA in forcing a large no-lead bullet zone and pushing for it to be statewide. I do not like to give money to people who restrict my rights.
