Actor and comedian Tim Allen continues to preach about the benefits of adding “more power” to nearly every situation. Gun makers throughout history have echoed Allen’s sentiment in their efforts to provide the most powerful guns for hunting, combat, and fun on the range.
Determining what is the strongest gun in the world in each firearms category is no easy question, but as the number one firearms auction house in the industry, Rock Island Auction Company is well-equipped to compare some of the rarest heavy-hitters available. RIAC’s Feb. 16-18 Sporting and Collector Firearms Auction, as well as its other upcoming events, include some of the most powerful guns designed for hunting and shooting that can be owned and enjoyed by the average collector.
Most Powerful Rifles
For big game hunting, the most powerful rifle models are needed to bag some of the world’s largest beasts. The Winchester Model 70 offered sportsmen a sturdy bolt action platform that would eventually be adapted for every powerful cartridge apart from the largest double rifle calibers. Thanks to strong factory chamberings and custom-modified Model 70s pushing the limits even further, this powerful gun model remains a popular option when taking on Africa’s “Big Five” today.
.50 caliber is the largest cartridge a civilian can own without an NFA exemption. Rifles with larger bores, such as African double rifles and their hard-hitting ammunition, are exempted for sporting purposes, for example. Among the most powerful gun models that can be widely owned by civilians is the Barrett M82 in .50 BMG. If you’re looking for hard-hitting range action and an unforgettable shooting experience, a quality .50 BMG rifle can’t be beat.
The double rifle platform is the strongest gun in the world fielded for hunting African game. When facing a changing Cape Buffalo, rhino, or an enranged bull elephant, stopping power is a matter of life or death. The Nitro Express series of cartridges was introduced to equip large bore hunters, ranging from the popular .470 Nitro Express to the more recent .700 NE. Of course, the king of the double rifle platform and the most powerful gun of its genre was and still is the mighty 4 bore.
Modern ammunition makers like Peter Hofer continue to push the boundaries of sporting rifle ammunition. The Austrian gunmaker recently developed a 4 bore Magnum double rifle, a candidate for the most powerful gun ever developed in the double rifle market and designed to fire a 1-inch-diameter 2,000-grain bullet at a staggering 2,624 feet per second. Monstrous figures, no doubt, but one offering from SKS Industries was created that eclipses even Hofer’s powerhouse.
Most Powerful Guns from J. D. Jones
Gunmaker, cartridge designer, and SSK Industries founder J. D. Jones forged a name for himself with quality hunting arms and ammunition. He also created some of the most powerful rifle models ever designed for civilian shooting, including the 14.5 JDJ and the .950 JDJ.
The 14.5 JDJ cartridge is based on the standard .50 BMG with the neck opened to accept the SSK 1,173 grain solid brass 14.5mm bullet. Needless to say, a round this large required SSK Industries to obtain an NFA exemption. This devastating custom cartridge makes the McMillian Bros. 14.5 JDJ bolt action rival a worthy candidate in our list of most powerful gun candidates, but its larger sibling, the .950 JDJ “Fat Mac,” dwarfs all competition.
The biggest gun in the SKS Industries family and a strong contender for the most powerful rifle outside of antitank military guns, the .950 JDJ Fat Mac chambers a 20x110mm Vulcan Cannon cartridge that’s been cut down to 70mm case length and necked up to 24mm (.95 caliber.) The JDJ’s fires a 3,600 grain bullet at 2,200 fps for a whopping 38,685 foot-pounds of muzzle energy. For comparison that’s well over three times the muzzle energy as even the strongest .50 BMG loads.
Most Powerful Handgun Models
Some of the most powerful handgun models of the black powder era included the Colt Walker and the Howdah pistol. While the big bore Howdah pistol was designed to ward off lions, tigers, and other dangerous game, the Walker was an oversized cavalry sidearm. The Colt Walker would retain the title of most powerful revolver until 1934 and the birth of the Magnum Era.
In the 1930s, wildcatters like Elmer Keith spurred a renaissance in ammunition development and pushed for stronger revolvers that could chamber their experimental cartridge loads. Col. D.B. Wesson, Vice-President of Smith & Wesson, answered the call with the .357 Magnum. Widely advertised as “The Most Powerful Pistol Made,” the .357 Magnum revolver was widely praised by law enforcement agencies and handgun hunters alike for its higher muzzle velocity and penetrative power.
“The Magnum Era” continued in the 1950s with the .44 Magnum cartridge. Smith & Wesson’s large N-frame revolver, chambered in the world’s most powerful handgun round to date, went into production in 1955. Hyped as the world’s biggest revolver, what would eventually become known as the Model 29 saw overwhelming success, and its reputation further skyrocketed in 1971 thanks to Clint Eastwood’s ‘Dirty Harry.’ Numerous gun makers would eventually release their own .44 Magnum revolvers, including Colt’s mighty Anaconda, the most powerful handgun in Colt’s “Snake Gun” series.
Revolvers from Ruger, Colt, Taurus, Korth, and other noted manufacturers were designed to take advantage of the potent .44 Magnum cartridge. One of the most unique handguns to chamber the .44 Magnum was the Italian Model 6 Unica. Among the scarce few true semiautomatic revolvers, the Model 6 Unica was engineered to reduce recoil by firing off of the revolver’s lower chamber instead of the top, where the force of recoil was better aligned with the shooter’s hand. This greater control worked well with some of the powerful cartridges appearing in the commercial market, including Dick Casull’s famous .454.
Most Powerful Handguns Today
The most powerful gun models in the handgun family evolved to chamber an ever-expanding line of monster cartridges being introduced in the decades following the .44 Magnum. In terms of commercial semiautomatic pistols, the strongest gun in the world title includes contenders like the Wildey Survivor and the mighty Desert Eagle.
Revolvers have seen even more of a cartridge arms race in recent years than their semiautomatic cousins. Today’s most powerful handgun models are designed to chamber titans like the .454 Casull, .480 Ruger, .475 Linebaugh, .500 JRH, and .500 Linebaugh. Some firearms fans dub the .500 S&W Magnum and the Model 500 X-Frame series the most powerful revolver pairing, and the platform certainly makes a case for itself.
Appearing on the commercial market in the early 2000s, both the .460 S&W and .500 S&W are true titans in their field. For production arms, the most powerful gun in the single action revolver family might just be the Magnum Research BFR, which can be chambered in either of the aforementioned rounds. In terms of the most powerful gun model for factory double action revolvers, when measured by sheer muzzle velocity, Smith & Wesson has an answer, boasting that their Model 460XVR is “the highest muzzle velocity of any production revolver on earth.”
Most Powerful Shotguns
The 10 gauge shotty is the most powerful gun platform legally allowed for waterfowling in the United States today. While the 10 gauge is somewhat of a rarity in the current sporting market, that wasn’t always the case. Before smokeless powder hit the scene near the end of the 19th century, the 10 gauge side-by-side offered hunters, storekeepers, lawmen, and security personnel a means to pack a big punch, as illustrated by the 1887 manufactured Parker Brothers hammer shotgun pictured below.
When it came to fowling, even more powerful guns were available for the wealthy elites of the 19th century. These behemoths were far from common, however. For example, from 1867 until the Federal Firearms Act of 1938, Parker Brothers only manufactured 246 shotguns in 8 gauge. 4 gauge shotguns were even more scarce, and today these specially ordered powerhouses are some of the rarest sporting arms in the collecting field.
Before the U.S. government banned the use of anything larger than 10 gauge for hunting migratory birds in 1918, the mammoth punt gun was the most powerful gun platform available to market hunters seeking to bag dozens of birds in a single shot. Manufactured in 4 gauge, 2 gauge, and even a colossal 1 gauge variant, the most powerful punt guns were more similar to small artillery than hunting arms.
English sports writer John Henry Walsh noted one London maker offered punt guns that were 1 1/2 inches in bore diameter, weighed 120 pounds, and carried 2 to 2 1/2 pounds of shot. An illegal punt gun seized by the U.S. Fish and Wildlife Services in 1920 was recorded as measuring nearly 11 feet long and weighing a staggering 250 pounds, certainly one of the biggest gun models for hunting purposes, past or present.
