I am not a huge fan of magnums, and will only use them if I need them. Out in Colorado, for instance. Bought a Browning A-bolt hunter in 7mm Rem Mag as my first rifle, because I was in Colorado looking to hunt mule deer and elk. Gun store recommended either a .30-06 or the 7RM, saying the latter was a flatter shooter. It was, and it worked well. Since then I bought a 300 Winchester magnum. Never have fired it. Only bought it because the price was right. Got it in the late '90s. It was a limited edition (1 of 500) Model 70 Win from Reinhart-Fajen stock maker. Its fitted to a fancy tiger stripe maple stock. I got it for long-range elk hunting, but in Africa would only bring it if I was hunting in the Kalahari or other area calling for long range shots.
I favor easier recoil, and am apparently your average shooter, as the .30-06 is about as much as I care for in terms of recoil. My .35 Whelen is heavier, but acceptable as long as I don't load with heavy rounds. I actually might consider putting a muzzle break on that one.
I have a 6mm Remington, .257 Roberts, and 6.5mm Swede, and all are a joy to shoot. Again, the only problem with my Swede is it's really a show piece, too fancy for the field. I was looking to get another 6.5mm which I wouldn't be afraid to get scratches on, and thought either another Swede or perhaps something along those lines, without going to the magnums. Again, the 264 Winchester is too similar to my 7mm Rem Mag to bother with. I would just default to the 7RM if it came to that. As discussed earlier, I was looking more at the 6.5 x 284 because it appears to provide more than the Swede but not go overboard like the magnums.
For this first hunt I'm not going to need a magnum, because it will be pretty much bushveld hunting; either in Limpopo or Mpumalanga or the northern part of Kwazulu-Natal. The outfitters I've been talking to all say that their areas will be such that most likely the longest shot I may face is 250 yards, with many being much closer. At that range, a good classic, rather than a magnum, is called for. Ergo, the .35 Whelen for the heavy stuff. Looking for this to be a lighter rifle.
