The quality and type of rifle that you might end up with in Africa can be anywhere from great to miserable. According to the video, "Boddington on Buffalo" (lots of good information on that one by the way - even if you're like me and don't like Boddington) Chifuti Safaris in Zimbabwe use Dakota rifles with Swarovski scopes as their camp guns. This should not be taken as the norm, and often the camp guns are iron sighted and poorly maintained. When I realized that there was not enough time left to get the in-transit documents completed and would have to leave my rifle at home, Mark Sullivan arranged for me to use a fine .500 NE double rifle of British lineage.
The problem is that you, the client, have little control over the type, fit, or quality of firearm that you might end up with. Had I had only the double rifle, taking plains game would of been a problem, but the other client on the safari was very generous with the use of his scoped M-70 .375 H&H. The problem here was big Mark was about 7' tall (or so it seemed) and the length of pull of his Custom Shop M-70 was better than 3" longer than my own rifle. The result was that my shots were consistently hitting 4"-6" below my point of aim. Had I had the opportunity of putting the rifle on paper I would of realized this and compensated accordingly (one does not start messing about with the adjustments of a rifle loaned under such circumstances) but I had taken both my wildebeest and my buffalo before I caught on to how I should aim.
The double became a bit of a nightmare. I could shoot it alright, but the turn of the century recoil pad, (not the recent turn of the century) wasn't much softer than the wood of the stock, and the piece recoiled enthusiastically as it spit out 570 gr X bullets at 2150. I had some difficulty learning the technique of breaking the gun over the knee to get it to open. Express sights normally have a wide shallow V rear sight and a bead front. This rifle had a narrow rear sight with a very deep V and tended to cover up much of the target making it slower, at least for me, to use. My general opinion on the use of a double rifle for dangerous game has suffered as a result.
I have been shooting powerful rifles for quite some time, and I am not terribly squeamish when it comes to recoil. The fact is that 10, no make that 5 rounds fired in a short period of time required that I concentrate very hard on the mechanics of the shot to push the thought of recoil from my mind. By 10 shots, I was becoming indelicate on the trigger, and actually had the rifle double on me when I harped the triggers. The felt recoil was no worse when the piece doubled (the closely spaced the shots were still two separate events) although the muzzles rose higher. One can only wonder how a client who had less experience shooting powerful rifles and a less generous hunting partner might of made out. I suspect he would pay less for trophy fees.
