Barnes VOR-TX, .357 Magnum, XPB HP, 140 Grain
An all copper projectile retains the most weight of any projectile type, while offering excellent penetration through the bones, heavy muscle and thick hides of tough game like hogs, and other intermediate sized game. The fast velocity and lightweight bullet offer significant penetration, while the exceptionally uniform expansion creates a wide wound channel for maximum blood loss.
The hard-hitting copper bullet still offers maximum stopping power despite being lighter weight than some competing projectiles. Satisfies most jurisdictional regulations for larger game hunting with the hollow point, all copper projectile and power/ballistics.
- All copper projectile
- Heavy energy transfer and excellent penetration in tough animals
Intermediate and large game hunting for the .357 magnum out of a revolver. This is a contender for the best 357 Magnum ammo for hunting of tough animals at moderate ranges due to the penetration potential and the hard copper projectile that offers extreme reliability in the mushrooming and diameter expansion.
General Information about the .357 Magnum
It’s known as the cartridge that started the “Magnum revolution” in handgun cartridges; and is based off the .38 Special cartridge. Famous gun industry figures including Elmer Keith (writer, hunter, tinkerer, sometimes thought leader) and D.B. Wesson (of Smith & Wesson Fame) and Phillip Sharpe (Strong NRA connections, vocal advocate for anything gun related) had a hand in developing the cartridge, which would quickly become the standard for police and special agent duty weapons in the law enforcement organizations across the United States including the FBI.
The 1934 introduction made the .38 Super for law enforcement use all but obsolete. The agencies and officers nearly all, preferred to have less rounds of the .357 Magnum than the 1911 based .38 Super and revolver based .38 Special rounds because of the inherent power and stopping power. It was a major shift towards performance when it came to matching the firepower on the streets against criminals and gangsters that were now starting to implement bullet proof vests and heavy steel car doors to shield themselves from police bullets.
What is the .357 Magnum used for?
Mostly, the .357 magnum is known for its prowess as a duty cartridge for law enforcement and as a potent cartridge for personal defense and home protection, where the fast projectile can penetrate deeply enough and create a large enough transfer of energy so as to immediately stop most threats. It has been one of the premier cartridges for such use since its inception onto the market in 1934, where it was immediately used by many police agencies across the country as noted above.
It is also a great handgun or lever gun cartridge for hunting of animals in the intermediate and large size range. Hunters everywhere have used it as a secondary backup firearm on big hunts or as a primary handgun or lever gun for intermediate sized game at intermediate and shorter ranges for decades. The high velocity and high energy transfer with the penetration and modern designed projectiles (more on that later), which offer high weight retention, this is a perfect cartridge for many types of game.
The well-known, well-loved .357 Magnum can also be used easily for plinking or range training, and target shooting. In fact, it has had a great resurgence in the competition world in a sport called Cowboy Action Shooting in the recent years. This sport puts reenactment into a competition form, in a sense, and challenges competitors to shoot old time cartridges in replica or other guns that were in use prior to 1899; with a specific set of challenges and loads. The round is a popular one among this crowd.
What do the different aspects of Ammunition performance mean?
Static ballistics are the numbers that are produced by the ammunition projectile in factory testing or by the standard pressures of the load in an optimum setup. It is comprised of the velocity and the energy delivery at the muzzle exit point, before significant wind drag or other environmental effects can degrade the power of the bullet. It is a good indicator of the build of a cartridge relative to industry competitor loads.
This is the amount of efficiency that a projectile has during it’s flight path. It can encompass several aspects, but it essentially means the bullet’s efficiency at shedding wind in direct flight towards a target. It is a direct measure of the effect of drag on a projectile size, weight, shape and profile,
This metric is used to show how much wider a wound channel can be made by the change of the bullets dimensions at or shortly after impact. The wound channel is affected by the size difference between the bullet as it enters and the bullet as it changes diameter through design moving through a target.
Generally, the larger the diameter change, the better the impact on the wound channel, which would increase the devastation, and therefore the stopping power of a given projectile, within reason. This has been proven to be less effective than some other aspects of projectile performance, as the diameter sometimes does little more to cause more trauma or decrease the time it takes to stop a target.
The more that a bullet retains weight, the better the jacket and the core lead (or other material) held together. It also shows how much the bullet can be expected to shed, or not shed its kinetic energy as it travels through the target. The greater the retained weight, the less energy loss inherent to the projectile and the greater the stopping power at impact.
The total amount of weight that a projectile holds. This is a variable in calculating and delivering mass on target through kinetic energy transfer. The larger the bullet weight, generally the larger the energy delivery (though there are some exceptions to this rule).
The amount of speed that a bullet is traveling. Generally, the faster the round is traveling, the better penetration there will tend to be, given the right mix of grain weight and velocity. Also, the velocity can aid in things like impact energy, and in the case of some animals, the amount of shock to the system through a controversial topic called “hydrostatic shock theory”.
While this is a highly debated subject it’s beyond the scope of this article, except to say, that there has been compelling data to show that some animals are given an almost instantaneous death due to a bullet traveling above a certain speed and increasing the chance for devastating consequences related to the impact a high speed projectile has on a target with a high volume of liquids.
Whether you agree it’s a real thing or not, there is a dearth of credible unexplained data that shows this phenomenon has at least some roots in reality.
Penetration varies on different targets. More than that, the debate about what is and is not a proper penetration depth and performance is a heated discussion at most times. Suffice it to say, adequate penetration is important. All the projectiles in the cartridge on this list are at a penetration depth which is within the depth of penetration that the FBI sets as a standard for the best defense and Duty ammunition.
Now that you know what the different aspects of the performance matrix deliver, the list of top quality ammunition choices will be easier to understand for their given purposes as outlined.What follows is a list of the best .357 Magnum cartridges for a variety of uses in real world scenarios.
The .357 Magnum is one of the more versatile pistol cartridges in the world for shooters who want something that can bridge different use cases. The value for your shooting dollar is exceptionally high and the performance has been market leading since it was introduced in the 1930’s.
The best .357 magnum ammo for each use case is outlined above. Make no mistake, there are other great rounds out there, and many loads that could easily replace the above list items, but for the money, and given the specific use of each of these loadouts, this list is a very good indicator of the stacked lineup of .357 Ammunition that exists on the market.
It is a loaded field of competitors because it is one of the most popular rounds in the United States and it enjoys a very good reputation for performance that is still able to be handled adequately by most shooters.
