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.

    Berry's Bullets have earned a reputation for quality and consistency. These 158 grain 38/357 projectiles are a great choice for affordable loads that are higher quality than traditional lead round nose projectiles. Each of these bullets are swaged at room temperature and copper-plated to their final weight. After plating these bullets are re-struck to ensure each projectile has a uniform plating and is symmetrical.

    Note: Plated Bullets are not recommended for velocities over 1,200 feet per second.

    Be sure to check out Widener's extensive collection of powder, primers and cases, for all of your re-loading needs.

    Wideners and Berry's deliver!

    Berry's makes a great product that performs well in the press and also on the range. With the current shortage of ammunition, and zero availability on 38 SPC and 357 Mag, having projectiles to replenish my training rounds is invaluable. Widener's was in stock and delivered fast. Now if if I could find more primers and powder, I would be even more satisfied.

  2. Armscor .357 Diameter Bullets - 158 Grain FMJ – 1500 Count

    Bullet Type Full Metal Jacket (FMJ)
    Manufacturer Armscor
    Manufacturer SKU 52271

    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!

    I bought these for my Desert Eagle XIX 357

    I used Accurate #9 and CCI 400 & 450 primers starting at 11.3 grns and ladderred to 12 grns. I enjoyed plinking with them and will highly recommend to any reloader .

    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.

    Review by Den (Posted on 1/6/2021)

    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.

    silhouette shooting

    Absolutely amazing bullets. I can consistently hit chickens at 200 yds. with a 10" contender with Belm .357 Max chamber and IMR 4227! The only bullet with a 2nd crimp groove for the .357 Max!

    Review by steel shooter (Posted on 9/14/2018)

    Good hog and deer medicine.

    Excellent for use on hogs and deer in carbines with heavy loads of Lil'Gun or H110.

    Review by Jeff Johnson (Posted on 12/3/2017)

    Excellent heavy bullet

    I loaded these in new .357 magnum cases with heavy charges weighed individually. The cartridge was accurate and the recoil noticeable from my 4 inch Python. These 180 grain bullets will likely be fine for the smallish central Texas deer. The bullet might be suitable for the myriad wild hogs. I certainly recommend this bullet.
