Behind the Bullet: .300 H&H Magnum by PHILIP MASSARO

300hhmagnum_lead.jpg

I looked through the spotting scope and answered Dave deMoulpied’s question. “Half-inch apart; send the third one.” That third one printed one inch from the other two, making a 1 ½-inch group at 200 yards, and a very happy shooter. I, on the other hand, was experiencing a torn heart as a result of being very happy for a close friend who’s rifle proved to be wonderfully accurate, and on the other hand the remorse of having sold that rifle to my best buddy. Ah well, it went to a good home, and I still get visitation rights.

The rifle? A 1959 Colt Coltsman, with a barrel inscription that reads simply ‘.300 Magnum.’ In 1959, there was no other .300 Magnum—save the .300 Weatherby—than the .300 Holland & Holland Belted Magnum; the .300 Winchester Magnum was still four years away and the H&H ruled supreme.

Released in 1925, the .300 H&H—or Super .30 as it is also known—was the fourth cartridge from Holland & Holland to wear that now-famous belt of brass, after the .375 Velopex, the .275 H&H and the workhorse .375 H&H. It caught on well, offering a significant increase in velocity over the .30-06 Springfield, and was available in the American-made Winchester Model 70 in 1937. Two years prior, Mr. Ben Comfort used the .300 H&H to win the Wimbledon Cup at the Camp Perry shooting matches, using a custom handload. Yup, the .300 H&H was, is and always shall be a shooter.

In our era of ever shrinking cartridges (one day they’ll look like a bullet sitting on top of a dime), we have obtained H&H velocities in .30-06 and .308-length cartridges, but there remains something very special about the design that Holland & Holland released over 90 years ago.

Its sloping shoulder (the Super 30 uses an 8˚-30′ shoulder) makes for extremely easy feeding, and though the 2.850-inch case requires a magnum-length action, using a classic cartridge like this is pure joy to a guy like me. It’s surprisingly easy on the shoulder—much more so than the .300 Weatherby—yet achieves velocity just behind the .300 Winchester Magnum, and with some handloads I’ve beat it.

As a hunting round, it is a wonderful choice; unlike many of the larger capacity .300 magnum cases, the .300 Holland & Holland works very well with some of the lighter bullets, including the stubby 125-grain pills. It also can take full advantage of the heavier 200, 210 and 220-grain slugs, making it a perfectly viable choice for all North American game, and all African game shy of elephant, lion, buffalo and hippo.

As a deer/antelope cartridge, I like the 150 and 165-grain bullets, though you may want to consider the premium designs, especially if impact velocities may be high due to a close shot. For elk/moose/bears, the 180-grain bullets absolutely shine. Muzzle velocities run between 2875 and 2950 fps—enough to deliver a very useable trajectory, and the higher B.C. designs will resist wind deflection very well.

Were I to take a Super .30 after the big bears of Alaska, I’d want a premium bullet of 200 or 220 grains, as those beasts can take a hammering, though many have fallen to a properly placed .30 caliber bullet.

Though the Super .30 has most definitely been pushed out of the lead role among .30 caliber magnums by the .300 Winchester, there are still some good factory loads available for it. The Federal Premium Trophy Bonded 180-grain load is wonderfully accurate, as is the Hornady Dangerous Game series featuring the 180-grain InterBond bulletNosler’s Custom Line and Trophy Grade ammunition offer the full gamut of their excellent bullets, loaded very well in pristine cases.

Handloading the .300 H&H is no problem; a good large rifle magnum primer and a healthy dose of medium to slow-burning powder and you’ll find the accuracy rather quickly. Mr. deMoulpied’s load was built around the 180-grain Swift Scirocco II and a goodly amount of Alliant’s Reloder 22, sparked by a Federal GM215M primer. It’ll maintain sub-MOA groups out to 300 yards—the furthest we’ve tested it—and is one helluva hunting rifle.

I’ve often thought that a hunter could easily take any and all game in the world with cartridges released before 1926, and I still believe that to be true. While I have fully embraced a few newer designs—the 6.5-284 Norma, the .300 Winchester Magnum and .416 Remington Magnum among them—I believe that 1925, the year both the .300 H&H and .270 Winchester were released, represented a landmark year in cartridge development, and most everything else has been a refined design of an old idea.

In a practical sense, the .300 H&H may pose an issue to those who want to ensure they can find ammunition in every Mom & Pop store in the backwoods. But to the hunter looking for something different—something classic, cool and yet effective—the .300 Holland & Holland is an excellent choice.

Behind the Bullet: .300 Winchester Magnum by PHILIP MASSARO

btb_300_win_mag_f.jpg

In 1963, after Winchester had released its initial trio of belted magnums—the .264, .338 and .458 Magnums, all based on a shortened .375 H&H case—they announced the coming of the .30 caliber version. Most folks anticipated a case of similar dimension and datum line (the distance from base to shoulder) to the .338 Win. Mag. and .264 Win. Mag., just necked to hold a .308” diameter bullet. However, Norma had filled that void a few years prior with their .308 Norma Mag., which is very similar to the .30-338 wildcat. Winchester thought outside the box, and developed a case completely different from the prior three.

The .300 Win. Mag. represented (until the advent of the .30 Nosler) the most potent .30 caliber cartridge one could get, at the standard “long”, or .30-06-length action. Winchester took the .338 case, at 2.500” in length, and extended it 0.12” to 2.620”, while reducing the neck dimension to 0.264”, in order to maximize case capacity. The resulting cartridge was, and is, what I consider to be the finest .30 caliber cartridge ever made.

Yes, the .30-06 Sprg. is an undeniable classic, and probably holds the honor of being the single most popular cartridge among modern hunters. Likewise, the .308 Win. has proven itself as a viable and extremely accurate hunting cartridge, and the .30-30 WCF remains an undeniable player despite its age and a changing market. But, for me, when I think about a .30-caliber cartridge that can do it all and do it well, I think .300 Win. Mag. Being a .30-caliber cartridge is a good thing; there are an unprecedented number of bullet weights and choices, and there really is something for just about any hunting situation shy of Cape buffalo and elephant.

The .300 Win. Mag. will drive a 180-grain bullet to an average of 2,960 fps—sometimes faster—and delivers a trajectory that will make shots within sane hunting ranges completely feasible. It is faster than the benchmark .30-06—generally offering a 150 fps velocity gain—yet it has a recoil level that is manageable by most shooters; definitely less than the larger-cased .30 caliber magnums. Personally, I’ve used bullets weighing between 140 and 220 grains in a number of varying game fields, worldwide.

Dimensionally, some have criticized the .300 Win. for having that short neck—less than one caliber in length—but it has never posed a problem for me. Like the .30-06, you can tailor the bullet for the game at hand, whether it’s a pronghorn antelope or Dall sheep at quite a distance, or a bear at relatively short distances. The .300 Win. may be the optimal elk cartridge, and will cleanly handle moose.

The 180-grain loads are among the most popular for larger game, and most .300 Win. loads will show a preference for bullets of this weight, or very close to it. Most ammunition manufacturers offer good .300 Win. loads, from the Federal Premium loads, to Norma’s fantastic ammo to the WinchesterHornady and Remington offerings. Many of these loads take full advantage of the premium bullets, and that will only enhance the already great performance of the .300 Win. Bonded-core, monometal, polymer tipped spitzers, round nosed cup-and-core; all are present in the factory loads for the .300 Win.

Personally, I’ve used the .300 Win. Mag. as much, if not more, than any other caliber. I’ve used it for pronghorn antelope on the plains of Wyoming, for caribou in the taiga of Quebec, and for whitetails and black bear in the hardwoods and evergreen forests of the Northeast. I’ve also used the .300 Win. for gemsbok, waterbuck, kudu and other plains game across Africa.

For the reloader, the .300 Win. offers a very versatile cartridge, which is easy to load for. The belt—which was carried over from the Holland & Holland design—really serves no purpose, as the .300 Winchester will headspace off the steep shoulder. You may see some stretching just in front of the belt, and that’s a consideration for any belted magnum case. Use a good Large Rifle Magnum primer and a healthy load of slow burning powder and you’ll see good results. Handloaders can take full advantage of the big .300 case, as you can safely load it down to .308 Winchester velocities, or load it to full-house velocities if you choose.

You’ll see the .300 Win. Mag. in the hands of military snipers and big game hunters alike, with good reason: it is a very accurate cartridge. The case can easily handle the long, sleek bullets that possess the best Ballistic Coefficient for the long range game, and equally handle the heavy, round nose slugs that those who hunt at closer ranges prefer.

The .300 Win. was, undoubtedly, the cartridge that knocked the .300 H&H off the stage, and while I have a special place for the .300 H&H, the .300 Winchester just makes more sense. My own pet .300 Win. is a Model 70 Classic Stainless that has been all over with me; I know it well, it’s very accurate, and I have all kinds of faith in it. The .300 Win. has been the cartridge I’ve reached for most throughout my career, and I don’t think that’s about to change any time soon. The .300 Win. Mag. just plain works.
