357 Sig – 125 Gr JHP – Winchester USA (USA357SJHP) – 500 Rounds

Winchester’s USA line is known for affordable range ammunition, and its 357 SIG hollow point offers an expanding bullet at a price closer to practice ammo. This listing is Winchester USA 357 SIG 125 grain jacketed hollow point ammo, MPN USA357SJHP, sold as 500 rounds for 357 SIG owners who want hollow points for both training and home use.

Winchester rates this load at 1,350 fps with 506 ft-lbs of muzzle energy, consistent with the cartridge’s goal of matching a 125 grain 357 Magnum from a semi-auto pistol. The jacketed hollow point is designed to expand on impact, and a hollow point is generally preferred for self defense because it reduces the risk of over-penetration compared with an FMJ. Shooting a hollow point in practice also confirms reliable feeding with this bullet profile in your pistol.

This ammunition fits pistols chambered in 357 SIG, including the Glock 31, 32, and 33, SIG Sauer P226, P229, P239, and P320 in 357 SIG, and Smith and Wesson and Springfield pistols offered in the caliber. A common question is whether 357 SIG uses the same magazines as 40 S&W. In many pistols it does, because the case head is the same, and often only a barrel swap is required to convert. Another common question is whether 357 SIG ammo works in a 357 Magnum revolver. No. They are completely different cartridges.

Winchester USA357SJHP is new production ammunition, not reloads, made in the USA. Each round uses a reloadable brass case with a boxer primer and non-corrosive priming. This listing ships as 10 boxes of 50 rounds for a total of 500 rounds from one lot. The 50 round boxes make this a cost-effective way to keep a 357 SIG supplied with hollow points for range and home. Practicing with an expanding bullet confirms it feeds in your magazines.
