Head to Head: .300 H&H Magnum vs. .300 Winchester Magnum

posted on September 3, 2021

The stallion stood on the right edge of the herd, moving only when the herd did, bringing up the rear and protecting his harem in as inhospitable a setting I've ever seen. I was prone, on a gigantic slab of granite, with my hunting bag rolled up under the forend of my rifle. “When he turns broadside, take him. He’s at 265 yards, all the way to the right,” Jamy Traut instructed.

I steadied the crosshair and gently squeezed the trigger, sending the rifle into recoil as a 180-grain Federal Trophy Bonded Tip bullet began its journey through the Namibian atmosphere, coming to rest only once the Hartmann’s Mountain zebra had fallen. To have hunted the Namib escarpment, and to have taken such a majestic animal was fantastic, to have used the classic .300 Holland & Holland Magnum to do so was simply a bonus.

Equally important among my hunting memories, is my first kudu bull, taken in a 115-degree South African blast furnace, after Nick Prinsloo and I burned to a crisp on the tracks. That loping gallop, which makes those wonderful curling horns rock back-and-forth as if they were floating on the ocean, was the bull’s downfall, as I timed his pace and used a .300 Winchester Magnum to put him “in the salt.” In fact, I have taken a .300 Winchester Magnum with me on a great number of hunts, both here at home in New York and on distant adventures as well.

‘Improving’ on the performance of the .30-06 Springfield is no easy task, considering the propellants of the era, but the 1925 release of the .300 H&H Magnum, or the Super .30, made a splash. Ben Comfort would use the cartridge to win the Wimbledon Cup in 1935—the first Cup to be taken with a magnum cartridge—and in spite of Roy Weatherby’s .300 Weatherby Magnum in 1944, rifles marked “.300 Magnum” were .300 H&Hs, until roughly 1950. Holland’s cartridge was a direct descendant of 1912’s .375 Holland & Holland Belted Magnum, replete with the belt, 2.85-inch case length, and 3.60-inch overall length.

The cartridge headspaces off the belt, so a gently sloping 8-degree 30-minute shoulder was employed and allows for wonderfully easy feeding.  The .300 H&H Magnum betters the velocity of the .30-06 by at least 150 fps, and often much more when handloaded; in fact, you can approach the 3000 fps mark with a 180-grain bullet. The case does require a magnum-length action, though the cartridge was among the earliest offerings in the Winchester Model 70 and Remington Model 721 rifles. It is a fantastic hunting cartridge, giving all the energy one really needs from a .30-caliber cartridge, and can be exceptionally accurate.

Winchester’s series of ‘short’ magnum cartridges released in the 1950s proved that they could get the job done in a standard long-action receiver, and though Norma threw its hat in the ring in 1960 with the .308 Norma Magnum, Winchester countered in 1963 with the .300 Winchester Magnum. Designed to replicate the performance of the Super .30, but in a long-action rifle, the .300 Winchester has a shortened neck (measuring a mere 0.264 inches), minimum body taper and a 25-degree shoulder. The .300 Winchester has a case length of 2.62 inches—compared to the earlier Winchester Magnum’s 2.500-inch length—and an overall length of 3.340 inches. Like the .300 H&H, the .300 Winchester is designed to headspace off the belt, but the clever reloader can adjust the cartridge to headspace off the shoulder.

The cartridge is wonderfully accurate, and because of its popularity is as readily available as any ammunition is these days; the .300 Winchester Magnum remains one of the most popular hunting cartridges to this day. It will drive a 180-grain bullet to a muzzle velocity of 2960 fps, and will handle the lighter bullets as well as it does the heavyweights. It has seen military duty, as a sniper cartridge, it has been a celebrated target cartridge, and makes an excellent all-around choice for the North American hunter.

Which is the better design, and which makes more sense for the hunter? Well, the level of performance between the two is so close as to not even matter, and the recoil level is nearly identical as well. The magnum receiver required for the .300 H&H adds both a bit of weight and a longer pull, though that has never posed an issue for me. The H&H cartridge has strong roots in the hunting world, and is an undeniable classic in both Africa and North America. It was a favorite of John Nosler—he was carrying one when he encountered the Canadian bull moose which inspired the Nosler Partition bullet—and 96 years after its introduction it remains as solid as it was when released. Modern bullets make it even more effective.

But, in spite of the panache and pedigree of the .300 H&H Magnum—Robert Ruark put it in the hands of his fictional PH Brian Dermott to follow up a wounded leopard—the .300 Winchester Magnum has pushed it out of the limelight. The .300 Winchester is a fantastic cartridge and the sheer amount of available rifles, ammunition, and components (read cases) for the .300 Winchester Magnum dwarfs those available for the .300 H&H. I've owned multiple rifles for both cartridges, and would grab either for any hunting situation which would be properly handled by a .30-caliber cartridge.

If you’re a hunter looking for one of these, the .300 Winchester Magnum makes the most logistical sense, as it has become so common that it is available nearly anywhere, like the .30-06 Springfield. That said, if you find a rifle chambered for Holland’s Super .30, and you can find an ample supply of ammunition or handload for it, do not hesitate to take it afield; I recently acquired a Winchester Model 70 XTR Sporter in .300 H&H Magnum and love the way it shoots. It will pair up perfectly with my Winchester Model 70 Classic Stainless in .300 Winchester Magnum; though trying to decide between the two is like trying to decide which of your kids you love most.

NRA Files Lawsuit Challenging ATF’s “Engaged in the Business” Rule

The National Rifle Association of America (NRA) has filed a lawsuit challenging the Bureau of Alcohol, Tobacco, Firearms and Explosives’ (ATF) “Engaged in the Business” Final Rule. The ATF’s Final Rule unlawfully redefines when a person is “engaged in the business” of dealing in firearms and therefore required to be federally licensed.

Colorado Cat-Hunting Ban Could be on Ballot in November

A recent report from the NRA Hunters Leadership Forum sheds light on a potential cat problem in Colorado; that is, it’s a problem if you’re a hunter who enjoys and wishes to continue chasing mountain lions and bobcats, or you simply agree that wildlife management should continue to be based on science.
