357 Magnum Bullets

357 Magnum Bullets for Reloading

This page contains 357 magnum bullets used by reloaders who load their own rounds. If you're looking for something ready to shoot, please head to our 357 magnum ammo page.

The 357 Magnum is one of the most popular handgun cartridges ever created. Introduced by Smith & Wesson in 1935 as an improvement on the 38 Special, its case is approximately .12 inches longer than its predecessor – yet it can deliver up to three times greater energy. A fine choice for hunting, self-defense, and recreational shooting, it’s no wonder why even non-shooters know this whopper of a revolver cartridge by name.

It only stands to reason you should find a wide selection of 357 Mag bullets for reloading. 357 Mag bullets commonly weigh between 125 and 180 grains, although load data for even lighter .357 diameter bullets are available and 200 grain gas check bullets are often used for hunting. The heaviest 357 Mag loads can exert over 1,000 ft lbs of energy when fired out of a rifle barrel, putting the revolver round on par with the 223 Rem.

Full metal jackets are suitable for target practice as well as hunting light game when you want to minimize meat damage, and LRNs make especially economical target loads. High-tech monolithic copper bullets by manufacturers like Barnes are a great way to modernize the 357 Mag for compliance with laws that ban toxic projectiles.

    Please note: This isn’t loaded ammunition. Component bullets are basically fishing sinkers until they have cases, propellant and primers.

    Home cooking is always better than takeout. Handloaded ammo is always better than the factory stuff, too! If you prefer to put a personal touch on every round you fire, then you’re going to love what Berry’s is up to.

    At 125 grains and .357” in diameter, this makes the perfect bullet for either 38 Special or 357 Magnum. The bullet is well balanced thanks both to its swaged lead core and electroplated copper jacket, and its flat meplat is great for stamping holes into paper targets.

    An electroplated jacket isn’t just evenly distributed. It also leaves no part of the core exposed to propellant gasses, which prevents the evaporation of toxic lead during ignition. Berry’s restrikes their TMJ bullets once they have plated them, creating a durable bond in the process.

    These training bullets are .518" long. Loading them to velocities in excess of 1,250 fps may lead to core/jacket separation. Plated bullets are not recommended for firearms with ported barrels or compensators.

    Please note: These are component bullets, not loaded ammunition. You can not fire these bullets unless you load your own ammunition.

    Armscor is earning themselves quite a reputation here in America. Their Rock Island Armory pistols fill a nice niche for people who don’t want to auction off vital organs just to be able to afford a 1911. Their 22 TCM cartridge has promise, even if most of the people asking about it only want to know if they can fire it in a firearm chambered for 22 LR. (No.) And their component bullets, which are produced according to precise tolerances, consistently weighted, and deliver good accuracy at the range, are sought after by handloaders throughout the country.

    This meaty slab of .357” diameter bullets is just the ticket for handloaders specializing in 38 Special or 357 Mag. With 1,500 bullets you be able to load 250 six-shot cylinders worth of ammo, and as full metal jackets they’re at once clean shooting and economically designed. Armscor draws a concentric jacket for what is ostensibly a target grade bullet, so your shots will benefit from satisfactory rotational stability and resultant flat trajectories. Buy ten of these cases of bullets and use them to ballast your canoe!

    My second batch, awww yeah

    This review is for the second batch of Armscor 158 gn, 38/357 FMJ's I bought from Widener's.

    I'll start by saying that buying from Widener's has always been a pleasure. The prices are fair, the communication is crystal clear, the rather dense product is well-packed and all of my transactions-to-date have been 100% satisfactory. In summary, Wideners' is an excellent supplier to the reloading community.

    Now, regarding the bullets that just arrived. I've taken a random sample of 25 bullets just like I did with my first batch of 1500 and I measured & inspected each one. My random sampling method is rock-solid and thus my sample results can be used to make valid inferences on the entire lot of 1500 bullets. The results are great, statistically speaking. The weights and dimensions are on target with a low amount of random (expected) variation. Surface quality, bonding and other physical properties all look great. Absolutely no issues.

    From my perspective, I don't think there's a better value in FMJ bullets than Armscor.

    But I'll repeat. Armscor, please send primers!!!! :)

    38 special

    Makes for very good range ammo the 38 special and the 357 liked it for range ammo

    Review by Jb (Posted on 1/8/2021)

    Great value

    It's not my favorite bullet weight but it was the only one I could get under these unprecedented circumstances we find ourselves in. I jumped on these as soon as I saw them as I was running low on my favorite 125 gr bullet. It's a great value and felt good shot in 38 Spl cases. I haven't tried them in 357 cases yet, but confident that it will perform as well.

    Armscor makes good stuff at a great price

    I loaded up some of these 158 FMJ's for both my revolvers and my beloved Henry Big Boy Steel. The accuracy was outstanding in all cases.

    And, the bullets are a dream for reloading, easy to press into place, no hangups, nothing off kilter, etc.

    Armscor....send primers. Please! :)

    I've reloaded about 200 of these and they work fine.

    Nothing more to say; they load fine.
