357 Sig Bullets

This page contains just the projectile portion of a cartridge and is meant for reloaders. Please go to our 357 Sig Ammo Page for loaded ammo that's ready to fire.

Designed to deliver the power of a 357 Magnum out of a semi-automatic pistol, the 357 SIG’s flat trajectory and downrange energy advantage make it an excellent selection for self-defense. Yet the 357 SIG never found its footing in a country already enamoured with the 9mm and the 40 S&W, so finding ammo can be tricky.

Fortunately 357 SIG bullets for reloading are not uncommon at all. At .355 in diameter and 125 grains they are essentially identical to 9mm bullets, and as such are widely available.

As it is the 357 SIG’s parent case, it is theoretically possible to resize 10mm brass to reload 357 SIG bullets. The result is a case that falls slightly short of SAAMI spec, however. Purchasing new brass or repurposing spent 357 SIG cases is preferable.

Different sources will tell you that the 357 SIG headspaces on either the case mouth or the shoulder. You should let your handgun decide which type of headspacing it prefers. New reloaders should also take caution that the 357 SIG’s short neck may not properly seat some 9mm bullets, leading to setback. A .355 bullet with a wider bearing surface is optimal for the 357 SIG. The great abundance of .355 bullets on the market still give the handloader ample opportunity to reload this exciting cartridge!

    USE FOR 9/MM ONLY

    I've used these 124 grain FMJ bullets for years loading 9/mm rounds. I did want to use them for my 357/Sig but a round nose bullet will never work, a truncated cone nose has to be used. The 357/Sig has an OAL of 1.400". If using this bullet and seating on the bearing surface the OAL will be around 1.325" or about 0.185" over length. If you try to seat this bullet to maximum OAL the bullet will just fall into the 357/Sig case. Because of the round nose there just is not enough bearing surface to correctly seat or grip the bullet. A 147/gr RN may work. I have those also and will have to see if they will work. I have found that for a 357/Sig a 124/gr bullet has to have a truncated cone to work which shortens up the bullet nose and in turn there is more bearing surface to grip the bullet.

    My New Go TO Round

    These are of great quality and very consistent. I have ordered them 3 times and will order them again. Price is right and shipping is very fast. I have been more than satisfied. I use them in 3gun and IDPA. I highly recommend this product and Wideners.

    Review by Kevin (Posted on 6/11/2020)

    Great Projectile

    This is my 3rd reorder on these. The quality is excellent and the price is right also. I have shot almost 1000 of these in the last few months and love them. I like 147 grn for IDPA and 3 gun competitions. I will keep using them and would recommend them highly.

    Review by KBrooks (Posted on 5/13/2020)

    Looks but have some issues to work through.

    I had loaded the bullets in my 357 sig. I had a concern that in order to achieve the OAL for the load, that the case would be seating beyond the flat part of the bullet. I had emailed Zero about a week ago and had still not received any reply, I guess I’m too small of a fish to bother with. I’ll be making a trip to the range this coming week to see how they perform.
    I had also loaded these same bullets for my 9MM. I ran into problems with maintaining a consistent OAL. I had set up my die to achieve a 1.115 OAL length but found an incredible range of lengths ranging on some as 1.105 - 1.235. All my cases were previously trimmed which would affect more of the crimping process anyway. I had to basically hand adjust my press for 25 out of the 50 bullets I had started with.
    I can only speculate there might be a slight variance in the curve of the bullet which might allow it to contact the conical portion of the seating stem at different levels. In all fairness the issue could be with my die set which is a Lee 9mm 4 die set, though I had not run into any problems like this with any other 147 grn. round I had loaded, or even other weights for that matter, though none had the same shape end as the Zero’s.
    I might do some experimenting to see if I can correct the problem with the 9mm, I do enjoy a challenge.

    Review by CB (Posted on 3/9/2020)

    Nose of the bullet a little long for 357 sig

    Not all 9mm bullets work with 357 sig. The reason is a relatively short the cartridge with a short bottle neck, therefore for the bullet needs to have a short or squatty tapered nose, so the neck will hold the flat portion of the bullet without being too long. While the photo of this bullet appears to be so, in reality the tapered nose portion of this bullet is longer than it appears in the photo. The result is this bullet barely works with a 357 sig cartridge, necessitating the use of a caliper, to seat the bullet at a minimum to still keep the cartridge the maximum length without going over. Saying this, if you are willing to jump through these hoops, these bullets cycle well and proved to be very accurat

    Low Recoil - Great Accuracy

    I read a review on one of the forums where someone said they were getting 2" or less groups with this bullet at 50 yds in a 9mm Luger. I have not done that level of load testing yet, but I chose a mid-range load with a fast powder. I got excellent results in a match shooting this load on timed and rapid fire (25 yd accuracy with very low recoil). I would definitely recommend it. Looking forward to doing some 50 yd. load testing soon.

    Load up on projectiles for your next bench session with these top-grade projectiles from Zero Bullets. These bullets are made in Alabama with a true copper full metal jacket and flat point (FMJ-FP). Flat point projectiles, which still have a curved ogive for reliable feeding, are are great for training and matches because of the easily recognizable holes that they leave on scoring zones. These rounds measure .355 inches in diameter and weigh in at 125 grains which is a versatile medium weight for both .357 SIG and 9mm Luger loads.

    Bullets are great for reloading 357 SIG , accurate as well!

    Review by Nick (Posted on 3/7/2022)

    Cheap, reliable, accurate

    I tried these bullets with two different powders, Blue Dot and Power Pistol. My loads turned out very comparable to 125g Winchester white box but were less than 1/3 of the price. The bullets worked well in my gun and shot accurately. I plan on purchasing them again.

    This isn’t loaded ammunition! Please only order these component bullets, which lack cases, powder and primers, if you intend to load your own ammunition.

    We’re always happy when we can offer Zero’s component bullets for sale on our site. Our customers have a high opinion of them – and rightly so. The Alabamian manufacturer takes extra care to carefully control their bullets’ weights, diameters, jacket concentricity and core distribution so you can load to spec and appreciate stellar accuracy. Zero’s prices don’t break the bank, either!

    This particular bullet’s great for loading America’s favorite 9mm cartridges, but we reckon they’re a great way to make the much rarer 357 SIG or 38 Super as well. In addition to good accuracy, the JHP will deliver the terminal ballistics you’d want when self-defense is your goal. These bullets are great for handcrafting your own target shooting loads, too!
