357 Magnum Ammo

357 Magnum ammunition made for a common sight in police armories from its introduction in 1934 until the 1990s. The 357 mag's legion of associated revolvers and carbines have evolved into a CCW and target shooting role and the cartridge is still trusted by a lot of shooters for that today. The .357 Magnum typically fires a 125 or 158 grain bullet, with the ligher projectile trading a bit of penetration for higher velocity and, in the case of jacketed hollow points, more reliable expansion.

.357 Magnum loads typically produce velocities between 1,200 and 1,500 feet per second along with relatively heavy recoil. Look for an assortment of big name brands for sale here at Widener's like Federal, Winchester and PMC with bulk range packs in-stock for all your training needs.

While it's not a historically correct cartridge for Western or cowboy action shooting, the .357 offers nice, flat trajectories and compatibility with a variety of lever-action rifle and wheelgun designs. Action shooting loads are typically a bit less powerful than regular target ones to promote rapid, accurate fire.

    CCI's Blazer brand of ammo allows shooters to enjoy inexpensive prices while experiencing the same amount of reliability for which CCI's rimfire ammo and component primers are well known. Each of these .357 Magnum rounds was built upon an aluminum casing which is non-reloadable and heat-treated for strength. A clean-igniting Boxer primer is mounted to the base of the case and serves to start a measure of high-energy propellant. Atop the round sits a jacketed hollow point (JHP) bullet which weighs in at 158 grains.

    This is a common weight for the .357 caliber and has been proven both in streets and fields as a law enforcement choice and hunting load for many decades. The JHP has large, naked recess in its nose, a toothed cannelure at its crimp point, and a rounded head for smooth insertion into revolver cylinders and seamless feeding in autos like the Coonan pistol. The cannelure helps maintain accuracy under recoil and also binds jacket and core together during impact expansion; this allows the bullet to penetrate deeply into a threat as it mushrooms and projects its energy into vital areas in order to achieve a positive drop.

    Cost Per Round 83.7¢ per round

    This .357 Magnum ammo from Fiocchi's economical "Pistol Shooting Dynamics" line is an excellent option for plinking, practice, and match use. Each cartridge is assembled using a reloadable brass casing, a standard clean-burning powder charge, a non-corrosive Boxer primer, and a Full Metal Jacket projectile with a Truncated Cone (FMJTC).

    FMJTC rounds are popular with competitors because they leave nice clean holes in paper and cardboard targets without sacrificing accuracy and stability at longer ranges. The bullets weigh 142 grains which is a median for the caliber and will boast comparable recoil to most defensive loads without being so fierce as to discourage extended range trips.

    The cartridge casings are crimped to their respective projectile's cannelures which prevents bullet setback or dislodging caused by recoil while sitting in the cylinder. Fiocchi ammunition is manufactured in Italy using processes and techniques that have been passed down and refined since 1876.

    The green and white box of Remington's classic UMC line is frequently recognized by experienced shooters as a source of affordable, dependable, and consistently performing ammunition. Remington designed the UMC line for accessibility but still stokes it with high-grade components such as their non-corrosive Kleanbore primers which leave very little residue in your revolvers action. For this .357 load, the primer is set into the base of a reloadable brass casing which contains a uniform measure of powder and is capped off with a jacketed soft point (JSP) projectile.

    At 125 grains, the JSP is on the lighter side for the .357 Magnum caliber and lends itself to relatively light recoil which can be important when firing appropriately chambered J-Frames or the Kimber K6s. A pronounced, exposed lead tip promotes threat-stopping expansion during entry while a flat nose surface helps to create a larger entry wound upon impact. The flattened nose also makes these rounds safe for use in the magazine tube of a lever-action rifle for short range varmint hunting. A toothed cannelure fastens the bullet's copper jacket to its lead core in order to preserve momentum and also prevents jostling and accuracy loss under recoil.

    Remington Performance WheelGun 357 Magnum ammunition is the perfect way to shoot targets. Whether your particular firearm is a revolver, a semi-auto (like the Coonan), or a lever-action, then it’s going to love tearing through these American-made rounds!

    This cartridge features Remington’s 158 grain lead semi-wadcutter. Like a traditional wadcutter, the LSWC’s flat nose profile lets it carve a very clean hole through a sheet of paper. Unlike a traditional wadcutter, this bullet features a ballistically efficient tapering profile which would also help it feed more efficiently from a magazine. The LSWC is also safe for rifles, as its broad tip cannot accidentally ignite the primer it butts up against in a tubular magazine.

    This round’s pure lead bullet has the supporting components it needs to deliver consistent ballistics. That includes Remington’s top shelf brass, which slides effortlessly in and out of a chamber, as well as their sensitive and rust-proof Kleanbore primer.

    Reliable, accurate and destructive. That’s what Remington’s HTP line of ammunition stands for – even if the initials do technically stand for High Terminal Performance!

    This is a premium cartridge. Remington’s straight-walled brass cases are strong, uniform in diameter and footed with concentric rims to create the optimal chambering depth. Big Green’s classic Kleanbore primers are at once incredibly dependable and non-corrosive, and their propellant charges are loaded nice and evenly to treat you to steady recoil and ballistics.

    This round’s 158 grain bullet shatters the speed of sound upon exiting the muzzle. Impact alone will overwhelm the threat, but the SJHP spells out an even worse story during penetration. That’s when its nose cavity fills with soft tissue until it has unleashed double-diameter expansion, thus carving out a cavernous wound channel. The SJHP’s semi-jacket helps to keep a barrel cleaner by limiting its exposure to lead residue, and also fortifies the bullet for assured deep penetration. A flat nose profile makes this round’s bullet compatible with lever rifles as well!

    The Federal Vital-Shok brand is expressly designed to give hunters the greatest advantage with projectiles that put game animals down cleanly with little suffering. With these .357 magnum cartridges, the projectile chosen is the Barnes Expander HP, a design that is primarily scouted for muzzleloaders. This hollow-point bullet features a large mouth and all-copper body for excellent weight retention, impact expansion, and energy delivery that will push past layers of fat and hide before scrambling organs within the chest cavity.

    Each bullet is crimped into a reloadable brass casing which wears a coat of smooth nickel, improving its cycling capability and shelf-life with a corrosion-resistant finish. The bottom of the case is fitted with a non-caustic Boxer primer that is bordered with thin moisture sealant. This substance keeps humidity and sweat from ruining the rounds function without interfering with the primer's ignition: a valuable feature of ammo that can be carried anywhere on the hunt. In addition, the Barnes Expander's round nose facilitates easy loading into revolver cylinders and lever-action side gates while its hollow cavity makes the load safe for tubular magazine storage.
