Code 4 appreciate you adding your comments. I grew up next to the Kruger Park and as a teenager did a lot of shooting of problem animals. My favorite was riding out on my horse and my dog in the veld and chasing down game - a minor echo of Gordon Cummings and Baldwin. Our neighbor farmers had an ongoing battle with big cats and elephant raids. I don't at all claim to be an expert since I ve not shot 1000 plus elephants or for that matter any but I ve talked to both game rangers and Ph who have a lot of experience . I go back to Africa nearly yearly, use 375s but this year a 416 Dakota. Of note most of the culling in Kp and Rhodesia was done with 7.62 NATO Fn R1 rifles with 20 inch magazines just like my army issue with 458 backup. As far as 416 Rigby failures that has been rare, probably older factory loads and frontal chest shots but still an excellent round. Not quite as effective for elephant but like the 375s if not for multiple hunts would be fine. My comment about 600s is based on Pondoro Taylors huge experience with them. Of note, in Magnum magazine there was an article 7 years ago about a hunter placing 6 perfect shots followed by one by the ph for an elephant brain but did not bring it down so the ph used his 450Ne and that instantly felled it. and yes I do sometimes read African safari on line (thanks for the link at the top of your post) but this sight teaches more and has more discussion. I was hoping this post would be of value to LR members interested or headed to Africa. As far as doubles vs bolt there are clearly pros and cons. Doubles pro- fast, light in 450,470, two quick shots, iron sights for close work, natural for shotgun shooters, and romantic traditional African rifle. Cons - price, regulated to a specific bullet and powder, older ones the rifle steel is often soft, you may never want to shoot an antique, the older rifles may rupture, if ther are a lot of animals being shot like with culling multiple shots take longer, less accurate and most group only about 6" at 50 paces, the right barrel is more worn in an older one because most reload after firing one shot and yes when dirty muddy or wet can be difficult to closer during reloading. - some difference between types. Karamajo Bell stopped using doubles for this latter reason. Bolts - pro - accuracy, cheaper, 3-5 shots typical with magazine like CZ 550, readily available ammo, easier to scope , jamming uncommon with factory loads except Remmington ( high pressures and heat of Africa hence generally not recommended by Ph unless worked on to convert to Mauser action and non rotating claw extraction and added larger extractor), muzzle brake on larger ones, work horses, longer ranges and can use different rounds for both animals and ranges. Cons - slower second shot, can jam in African heat, not fancy or artistic for showing off and telling the story! Just a note about Rugers - occasional jam from Africa heat, single shot so slightly slower to reload, very accurate, based on Farquharson patent (probably copied from American Alexander Henry), reliable, more powerful than equivalent 375 H&H, 416 Rigby, lighter, more recoil, and can be made to chamber Jefferies 500 or even 600 NE. Selous describes using a Gibbs - Farquherson at the end of his career as his favorite rifle (after his profesinal hunting). My favorite is a single shot 375 and with practice it s fairly quick to reload. If you choose a lighter rifle, double or single remember you Ph is ther to back you up often also with an apprentice. Obviously shot placement, SD, performance, bullet type (solids for elephant brain, buffalo followup and premier heavy rounds like Barnes X, Rhino (particularly 380 Rhino in 375), Hornady, swift A frame,Trophy bonded bear claw etc are all critical. Africa is a wonderful experience and remember it is cheaper than Alaska and many guided elk hunts plus the weather is great, it s very exciting, and the food is great. Have fun!
