20 Rounds of 135gr JHP .357 Mag Ammo by Speer

The .357 Magnum hit the market in 1934 courtesy of the handloading expertise of Elmer Keith, who worked along with Phillip Sharpe and Colonel D.B. Wesson to create the powerful round. Its parent case is the .38 Special and, in fact, they share the same diameter bullet - .357” – but that doesn’t make them identical. In fact, some gun owners have experienced some confusion regarding the use of both cartridges in the same firearm. This is much like the 5.56 versus .223 issue. The .357 Magnum is loaded to a higher internal pressure than the .38 Special, and that means that although you can feed .38 Special rounds to your .357-chambered gun, you shouldn’t do the reverse. Using .357 rounds in a .38 Special gun that isn’t rate for them can be catastrophic.

These particular .357 Magnum rounds are fairly lightweight at just 135 grain, but that lighter weight both enables them to move down-range at a greater speed while also keeping felt recoil at a lesser amount as compared to heavier rounds. These are Jacketed Hollow Points (JHP) and deliver controlled expansion on impact. They expand at a slower rate than standard HPs, allowing them to penetrate more deeply, creating a truly crippling wound channel. Each round moves towards your target at a muzzle velocity of 990 feet per second and impacts with a muzzle energy of 294 foot-pounds. This ammunition is meant for self-defense.

There are 20 defense rounds in this single box of Speer ammunition. Speer was founded by Vernon Speer in 1944, who got the business started by renting space in the basement of a grocery store. It didn’t take long for the business to outgrow the rented space, though, and before long Speer was forced to find something bigger. The company ended up in a facility in Lewiston, Idaho, along the banks of the Snake River, and it’s stayed there ever since. Speer has a solid reputation in the industry for producing good quality, reliable ammunition. Don’t trust you or your family’s safety to just anyone. Order these Speer Gold Dot rounds and be prepared.
