It\u2019s an old Latin word that means \u201clarge, great, or important.\u201d That ancient definition is still applicable in describing modern magnum ammunition. Simply put, magnum ammo contains extra propellant compared to a standard cartridge of similar size.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a result, magnum ammo will provide higher gas pressure, high-velocity projectiles, more kinetic energy and will be more powerful when compared to other cartridges of the same diameter.

For instance, in the <\/span><a href=\"https:\/\/www.warnerbros.com\/movies\/dirty-harry\"><i><span style=\"font-weight: 400;\">Dirty Harry<\/span><\/i><\/a><span style=\"font-weight: 400;\"> series of movies, Clint Eastwood plays the title character, a no-nonsense police detective who carries a Smith and Wesson Model 29, a six-shot, double-action revolver chambered for the <a href=\"https:\/\/www.wideners.com\/handgun\/44-magnum-ammo\">.44 Magnum cartridge<\/a>.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Harry probably did more to create magnum mythology than any other character on the big screen or television. By warning a bad guy that his weapon is \u201cthe most powerful handgun in the world\u201c that could \u201cblow your head clean off,\u201d Harry gave the Model 29 and its .44 magnum ammo some impressive capabilities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While the <\/span><i><span style=\"font-weight: 400;\">Dirty Harry<\/span><\/i><span style=\"font-weight: 400;\"> films did wonders for gun retailers (they could hardly keep the Model 29 in stock), most gun enthusiasts disagree that any magnum ammo, including the .44, is powerful enough to remove a bad guy\u2019s head. But Clint Eastwood\u2019s character is tasked with entertaining moviegoers\u2014not educating them with accurate facts.<\/span><\/p>\n<h3><b>Magnum Ammo: Fact VS Fiction<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">While we are exploding myths, here are a few other tall tales and exaggerations about magnum ammunition that needs to be corrected:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Myth:<\/b><span style=\"font-weight: 400;\"> Magnums can travel \u201cdead flat\u201d for 500 yards. <\/span><b>Truth:<\/b><span style=\"font-weight: 400;\"> If you aim a 180-grain Silvertip directly on a target 500 yards away, it will drop five feet before it even gets there.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Myth:<\/b><span style=\"font-weight: 400;\"> A magnum will stop a charging big-game animal with one shot every time. <\/span><b>Truth:<\/b><span style=\"font-weight: 400;\"> Only if it\u2019s combined with <em>extremely<\/em> accurate shot placement.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Myth:<\/b><span style=\"font-weight: 400;\"> As shown in the <\/span><i><span style=\"font-weight: 400;\">Dirty Harry<\/span><\/i><span style=\"font-weight: 400;\"> film, you can blow a large man off his feet and through a plate-glass window using a .44 Magnum cartridge. <\/span><b>Truth:<\/b><span style=\"font-weight: 400;\"> Highly unlikely unless he&#8217;s already falling backward, but you will do some significant soft tissue damage.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Myth:<\/b><span style=\"font-weight: 400;\"> A magnum cartridge will double the speed and stopping power of a regular cartridge. <\/span><b>Truth:<\/b><span style=\"font-weight: 400;\"> False, in fact, it\u2019s mathematically impossible.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Myth:<\/b><span style=\"font-weight: 400;\"> Firing magnum ammo is like firing standard ammo. <\/span><b>Truth:<\/b><span style=\"font-weight: 400;\"> Magnums can kick like a mule.

Yep, that&#8217;s a thing. The .22 Winchester Magnum is an excellent varmint control cartridge.<\/p><\/div>\n<p><span style=\"font-weight: 400;\">A generic definition of magnum ammunition is typically \u201ca cartridge equipped with a larger charge than other cartridges of the same size.\u201d While this is essentially correct, it\u2019s still a long way from the complete story.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So how do ammo manufacturers create a magnum cartridge? They make room for more propellants to increase muzzle velocity. With rifles, that can be accomplished by making the case wider, longer, or increasing its shoulder angles\u2014or perhaps a combination of all three.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With handgun cartridges, it\u2019s merely a matter of lengthening the case. You can find an example of this in the .357 Magnum cartridge, which is made by extending the .38 Special case. Smith &amp; Wesson stretched out the case from its original 1.155 inches to 1.29 inches (a little over 1\/8\u201d). They both fire the same .357-inch bullet, but the extra powder in the magnum version gives it substantially more power.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The same holds for \u201cDirty\u201d Harry Callahan\u2019s .44 Magnum. The .44 Magnum is simply a stretched-out and more powerful version of the .44 Special case with a regular .44 caliber bullet in each.\u00a0<\/span><\/p>\n<h2><b>Popular Types Of Magnum Ammo<\/b><\/h2>\n<div id=\"attachment_6957\" style=\"width: 1034px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-6957\" class=\"wp-image-6957 size-full\" title=\"hornady 300 win mag ammunition\" src=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/BSS1561-Web.jpg\" alt=\"A photo of hornady 300 win mag ammunition\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/BSS1561-Web.jpg 1024w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/BSS1561-Web-300x200.jpg 300w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/BSS1561-Web-768x512.jpg 768w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/BSS1561-Web-790x527.jpg 790w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-6957\" class=\"wp-caption-text\">The .300 Winchester Magnum is a popular choice for hunting medium to large size game.<\/p><\/div>\n<p><span style=\"font-weight: 400;\">Now that we&#8217;ve discussed the basics of magnum ammunition, let&#8217;s take a look at some of the more popular cartridges in the chart below. Magnum ammo comes in a variety of different usage types, including handgun, rifle, and rimfire. There&#8217;s also a variety of bullet types available for magnum ammo, ranging from FMJ, JHP, LRN, and more to give shooters more options.<\/span><br \/>\n<!-- HTML Code --><\/p>\n<div class=\"b-wrss-table-wrap\"><table class=\"GeneratedTable\">\n<thead>\n<tr>\n<th>Magnum Handgun Ammo<\/th>\n<th>Popular Magnum Rifle Ammo<\/th>\n<th>Magnum Rimfire Ammo<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>.327 Magnum<\/td>\n<td>7mm Remington Magnum<\/td>\n<td>.17 Hornady Magnum<\/td>\n<\/tr>\n<tr>\n<td>.357 Magnum<\/td>\n<td>.270 Weatherby Magnum<\/td>\n<td>.22 Winchester Magnum<\/td>\n<\/tr>\n<tr>\n<td>.44 Magnum<\/td>\n<td>.375 H&amp;H Magnum<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>.454 Casull<\/td>\n<td><a href=\"https:\/\/www.wideners.com\/rifle\/300-winchester-magnum-ammo\">.300 Winchester Magnum<\/a><\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>.500 S&amp;W Magnum<\/td>\n<td>.338 Lapua Magnum<\/td>\n<td><\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<h4>Magnum Shotgun Ammo?<\/h4>\n<p><span style=\"font-weight: 400;\">What about shotgun ammo? There are magnum shotgun loads, however, the term &#8220;magnum&#8221; is used more for marketing than for performance. Shotgun shells are measured by length, a magnum shotgun shell isn&#8217;t any longer than a standard one. A &#8220;magnum&#8221; shell describes the number of gunpowder drams a shell of a specific length is loaded with. Generally, any shotgun shell loaded with greater than 3 drams of powder is considered to be a magnum.\u00a0<\/span><\/p>\n<h4><b>How Much Of A Difference Does Magnum Ammo Make?<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">The point of a magnum cartridge is to increase velocity and power.\u00a0 To accomplish this you must increase the size of the cartridge casing to allow room for more gun powder. Having a larger casing, with a larger capacity, allows for higher cartridge pressures and greater velocity. To state the obvious:<\/span><br \/>\n<!-- HTML Code --><\/p>\n<div class=\"b-wrss-table-wrap\"><table class=\"GeneratedTable\">\n<thead>\n<tr>\n<th><\/th>\n<th>Bullet Type<\/th>\n<th>Bullet Weight<\/th>\n<th>Velocity<\/th>\n<th>Energy<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>.44 Special<\/strong><\/td>\n<td>JHP<\/td>\n<td>200gr<\/td>\n<td>975<\/td>\n<td>423<\/td>\n<\/tr>\n<tr>\n<td><strong>.44 Magnum<\/strong><\/td>\n<td>JHP<\/td>\n<td>240gr<\/td>\n<td>1,475<\/td>\n<td>1,160<\/td>\n<\/tr>\n<tr>\n<td><strong>.38 Special<\/strong><\/td>\n<td>JHP<\/td>\n<td>125gr<\/td>\n<td>900<\/td>\n<td>225<\/td>\n<\/tr>\n<tr>\n<td><strong>.357 Magnum<\/strong><\/td>\n<td>JHP<\/td>\n<td>125gr<\/td>\n<td>1,450<\/td>\n<td>583<\/td>\n<\/tr>\n<tr>\n<td><strong>.41 Long Colt<\/strong><\/td>\n<td>LFN<\/td>\n<td>200gr<\/td>\n<td>650<\/td>\n<td>188<\/td>\n<\/tr>\n<tr>\n<td>.<strong>41 Magnum<\/strong><\/td>\n<td>JHP<\/td>\n<td>210gr<\/td>\n<td>1,560<\/td>\n<td>1,135<\/td>\n<\/tr>\n<tr>\n<td><strong>.32 Long Colt<\/strong><\/td>\n<td>LRN<\/td>\n<td>80gr<\/td>\n<td>840<\/td>\n<td>126<\/td>\n<\/tr>\n<tr>\n<td><strong>.32 H&amp;R Magnum<\/strong><\/td>\n<td>JHP<\/td>\n<td>85gr<\/td>\n<td>1,263<\/td>\n<td>301<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<p><span style=\"font-weight: 400;\">Increasing the speed in magnums also results in a flatter trajectory and a greater impact force (terminal energy). Magnum cartridges also offer consistent long-range accuracy, delivering the extra striking power needed for deeper penetration and bullet expansion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While the advantages of magnums over regular rounds are real, some of the improvements are relatively small. Below is a prime example.<\/span><\/p>\n<h3><b>30-06 Springfield VS 300 Winchester Magnum<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The .30-06 and <a href=\"https:\/\/www.wideners.com\/blog\/best-300-win-mag-ammo-the-best-long-range-hunting-cartridge\/\">.300 Win Mag<\/a> are two of the most popular big-game cartridges. The .30-06 has been the .30-caliber benchmark in standard ammo, and the .300 Win Mag is likely the most common .30 caliber magnum cartridge. So, how do they compare?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The .30-06 ammo averages 2,700 feet per second, pushing a 180-grain bullet from the muzzle. The Win Mag produces velocities of around 2,950 fps, or 250 fps more than the aught-six. But what does that extra case capacity give the shooter in a practical application?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The increased speed reduces bullet drop at 300 yards by about 1.3 inches. In other words, the .30-06 bullet drops about 8 inches, while the .300 Win Mag drops 6.7 inches. However, at 400 yards, the .30-06 drops a full 4 \u00bd inches more than the .300 Win Mag, perhaps making the Magnum a better choice for big game at longer distances.<\/span><\/p>\n<h2><strong>Is Magnum Ammo Worth Shooting?\u00a0<\/strong><\/h2>\n<div id=\"attachment_6945\" style=\"width: 1034px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-6945\" class=\"wp-image-6945 size-full\" title=\"man shooting a revolver\" src=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC4082-Web.jpg\" alt=\"a photo of a man shooting a revolver\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC4082-Web.jpg 1024w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC4082-Web-300x200.jpg 300w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC4082-Web-768x512.jpg 768w, https:\/\/www.wideners.com\/blog\/wp-content\/uploads\/DSC4082-Web-790x527.jpg 790w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><p id=\"caption-attachment-6945\" class=\"wp-caption-text\">If you&#8217;re planning on using magnum ammo for self-defense, be sure to get plenty of practice at the gun range.<\/p><\/div>\n<p><span style=\"font-weight: 400;\">Is magnum ammo worth it? If you\u2019re shooting at shorter distances and don\u2019t want to endure the fierce recoil, you might want to stick with standard ammo. Be aware that magnum ammo does have more of a kick to it than a standard cartridge. If you plan on carrying magnum ammo for self-defense, you&#8217;re going to want to put in enough range time to overcome the additional recoil and place accurate follow-up shots on target.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What about magnum ammo for hunting? If you hunt at longer distances, magnum ammo could be well worth it. The added velocity and knock-down power could attribute to greater target accuracy and more meat on the table.
