IMHO the difference for big game hunting is that winning the Weatherby Award when that was a big deal was more likely to happen with the Weatherby cartridge in a Weatherby rifle.
Beyond that no practical difference except price and availability of cases.
The Weatherby had a 20 year head start, and a tremendous reputation before the first Winnie came off the assembly line... It was an obvious choice for those who had seen some of the world in the war and wished to travel and hunt far away places...
O'Connor and Page both had Weatherby awards before the Winnie was introduced... (R.W. always had a flair for marketing)
The Weatherby was the king of the hill, and rightfully so, for some 30 years... But the practicality, and business-like simplicity of the Winnie could not be denied...
Rising like cream, to the top of the bottle, the Winchester fast .30 made huge strides, even after being orphaned by the rifle that spawned it... The Winnie is the Labrador retriever of the magnum rifle world. it simply does what a rifle needs to do, with less fuss and bother than any other fast .30...
It baffles me a bit to consider that the H&H is so revered by many in the U.S.
The Winchester (and the Weatherby) holds the same attraction for most who abide in other parts of the world...
