More Details About This HPR 158gr JHP .357 Mag Ammo

.357 Magnum ammunition first hit the market in 1934, and although the cartridge was technically the result of a team effort between Phillip B. Sharpe, Col. D.B. Wesson, and Elmer Keith, it was Keith who is responsible for the lion’s share of the credit. With the creation of the .357 Magnum the “magnum” era and style of handgun began. Aside from extensive work handloading .38 cartridges, Keith also contributed his Keith bullet which featured a large, flat meplat for fantastic energy transfer and rapid expansion on impact. Although the bullet was altered somewhat for the final .357 Magnum cartridge design the gist remains; these are fast, hot rounds capable of delivering a solid punch.

These rounds are made for your .357 Magnum by HPR. At 158 grain they’re fairly heavy rounds capable of striking targets with significant force, but they’re not too heavy to race down-range at incredible speeds. These rounds have Hornady XTP bullets which deliver rapid energy transfer and expansion on impact. As they mushroom they simultaneously decelerate for a massive wound cavity while also preventing over-penetration, which protects innocent bystanders. Each round has a muzzle velocity of 1560 feet per second and muzzle energy of 865 foot-pounds. This ammunition is designed for self-defense use.

There are 50 defense rounds in this single box of ammunition from HPR. With 50 rounds you can keep your pistol and spare magazines or speedloaders loaded and ready to go. These boxes are also a good size for stashing in your range bag when you’re heading out for self-defense training or storing on the shelf in your gun safe. These are brand new production, brass-cased rounds with boxer primer, so make sure you collect your spent brass and reload it for even more trigger time with your favorite pistol. HPR manufactures ammunition at their established factory in Payson, Arizona. All ammunition is loaded according to SAAMI specifications. Place your order now and be prepared for whatever may come.
