Since the .35 Whelen and the .350 Rigby Magnum are ballistically similar, I thought these articles about the .350 Rigby Magnum might be of interest.
I like the old classic cartridges used in Africa; a little nostalgia and the romance of safari in days gone by. In fact, one of the main reasons I purchased my Ruger M77 Hawkeye in .35 Whelen was to have a rifle that could duplicate the original ballistics of the .350 Rigby Magnum. Since I can't afford an original Rigby rifle in .350, I can at least duplicate the cartridge's original ballistics. (.350 Rigby Magnum: 225 gr .358" diameter bullet at 2625 fps according to my reprint of the
Kynoch / ICI catalog of 1936.) Plus, the .35 Whelen is a classic American cartridge. In my opinion, it pairs very well with my Ruger M77 Mk II in .30-06 Springfield.
By the way, my reasoning was the same when I purchased my Ruger M77 Mk II in .338 Win Mag. I think it makes a good substitute for the .318 Westley Richards (.330" dia) and the .333 Jeffery (rimless) cartridges. A rifle in .338-06 would have been a closer match ballistically but they're more dificult to find (or have built). And, the .338 WM gives me a little extra velocity compared to the older .318 and .333 cartridges. I can always load down my .338 Win Mag a little to match the ballistics of the .318 W-R and the .333 Jeffery if I want to and I have done so in the past. My .338 WM firing a 250 gr Woodleigh RN bullet at 2500 fps is very pleasant to shoot. A perfect load for the bushveld, IMO. (I had my fourth trip to South Africa booked for 2008 but I cancelled the trip in 2007. Remember the 2007-2008 financial crisis? I was planning to take my .338 Win Mag on that trip but, regrettably, I never made it back to Africa. Such is life.)
I hope you find the articles linked below to be of interest.
Just my two cents... Cheers! Bob F.

Ernest Hemingway takes aim with his Griffin & Howe Springfield, Serial No. 956, chambered in .30-’06 Sprg., which still retains its G&H scope mount, even though the famed author relied only on its iron sights to take numerous game animals on two East African safaris and on hunts in Wyoming, Idaho and Montana. “… most beautifully made and finished and simple, practical gun I’ve ever seen,” he wrote. Unfortunately, this rifle was stolen in the 1970s, and its current whereabouts are unknown.

Osa Johnson, a celebrated filmmaker, author, and adventuress from the 1920s and ’30s, is shown with her Griffin & Howe Springfield .30-’06 Sprg. on one of her many safaris, during which she guarded her husband, Martin, while he filmed African wildlife. On at least three occasions, she saved his life by killing charging animals. She also supplied meat for the camp, often using this rifle.
