Overview of Bulk 357 Magnum Ammo

The 357 Magnum was the first magnum handgun cartridge. Elmer Keith and Phillip Sharpe built it in the mid-1930s by lengthening the 38 Special case and loading it with more powder, and Smith & Wesson brought it to market as a law enforcement round that could punch through the cover Prohibition-era criminals hid behind. Nearly a century later, it is still one of the most trusted revolver cartridges for self-defense, hunting, and target shooting.

Because the 357 Magnum case is longer than the 38 Special, a 357 revolver will also fire 38 Special, but not the other way around. Full-power 357 loads push a 158 grain bullet at around 1,235 fps, and our 357 Magnum ballistics charts cover velocity, energy, and bullet drop for every factory load we could find. Buying 357 Magnum ammo in bulk keeps the range bag full without paying box prices every trip.

How will your 357 Magnum ammo be delivered?

Your 357 Magnum ammo purchase will be shipped straight to your door in a discreet, unmarked package.

What are the advantages of buying bulk 357 Magnum ammo?

  1. Lower cost per round: Cases of 250 to 1,000 rounds bring the price of each round down compared to buying the same load by the box.
  2. Always range-ready: Bulk buying ensures you’re well-stocked and ready for the range at any time, safeguarding against supply chain disruptions.
  3. Less frequent reordering: Buying in bulk reduces the need for frequent reordering, giving you peace of mind with a steady supply of ammo.
  4. Improved shooting consistency: Consistent ammo supply helps maintain accuracy and performance by eliminating variations between different batches. Defensive shooters can stock their carry load the same way, since our 357 Magnum hollow point ammo comes in 200 to 600 round cases.
  5. Prepared for any situation: With a bulk supply, you’re always prepared for any unexpected needs, be it a spontaneous shooting session or an emergency.
  6. Supporting worthy causes: Each purchase at Ammo.com contributes to a donation in your name to a Liberty Fund organization at no additional cost to you. Discover who we support here!

  • Michael said:

    I'm extremely happy. The ammo is great quality

  • Bcino said:

    It does what it supposed to do very intense intentionally

  • Jimbo said:

    Excellent ammo. Shot several hundred rounds from from my GP-100, Ruger Redhawk .357, and Henry Big Boy Steel with no problems. Great ballistics, and very accurate. Will buy again.

  • djhgrit said:

    Good ammo. Shoots good. Whish the ammo supply would get back to normal.

  • Paul said:

    I didn't really like the shape of these SWC. I would prefer Keith design for LSWC, So I decided to build my own with the age old 4.2 Bulleseye charge and 158 Gr Keith SWC shaped bullets.

  • Paul said:

    I bought a new Colt King Cobra. The owner's manual suggests I use only factory built ammo. This model is satisfactory ammo for this revolver.

  • Mick said:

    All rounds fired cleanly, great product.

  • Tyler said:

    Before I found this website I ordered from somewhere else and had an awful experience and had to wait 6 months to finally get my order and decided I wouldn’t buy online again. But I gave this a shot and am extremely glad I did. My order shipped right away and got here in like a week and I’m so excited

  • Tad said:

    Good ammo.

  • Shadow said:

    Fired around 100 rounds from a 1854 lever action. Rounds failed to feed or got stuck every now and then. Unsure of whether that's due to the rifle being new or the ammo not being good

  • F said:

    Ammo it loded hot just how I like it. Yes its not HP or JHP but since it has significantly more energy than avg 357 Magnum Ammo I feel I dont need it to be HP to get good effect. Also its among the least expensive Brass .357 Magnum Ammo while still performing quite well. What's not to like?

  • customer said:

    Good quality ammo, would buy again.

  • Daniel said:

    This particular ammo has significantly jumped in price. Now that I am shooting it accurately from 5 to 30 yards l will slow down on running it through my 158 gr Hp. Great hard hitting energy transfer.

  • Dan said:

    Extreme performance and superior energy transfer into target
