Precision One .357 Sig 125 Grain Hornady XTP – 50 Rounds (Box)

Precision One 357 Sig 125 grain Hornady XTP ammunition delivers the flat shooting, high velocity performance that made this bottlenecked cartridge a duty favorite. Fifty rounds to the box means you can spend a full range session working the cartridge instead of counting what is left. Every round leaves the muzzle at 1200 fps behind a proven expanding bullet.

The chambering was designed to push a 125 grain pistol bullet fast enough to mimic magnum revolver ballistics from a semi automatic. It does that job well, and it rewards ammunition loaded carefully, because a bottleneck case needs consistent neck tension to feed and chamber cleanly.

What the Precision One 357 Sig load offers

Two good components meet in this cartridge. The bullet is the Hornady XTP, short for eXtreme Terminal Performance, a jacketed hollow point with a long record of expanding without coming apart. The loading is done to tight specification so velocity stays consistent from round to round.

Shooters carrying a duty pistol in this chambering, and competitors running it in steel and action matches, are the natural buyers. A 50 round box makes the Precision One 357 Sig practical for regular practice rather than a once a year novelty. High velocity cartridges are only worth carrying if you shoot them enough to master the muzzle rise.

Features that make the Precision One 357 Sig stand out

• Hornady XTP hollow point tuned for optimal expansion and penetration at real world velocity.
• 1200 fps muzzle velocity for a flat trajectory and a short flight time to the target.
• Reloadable brass cases, a genuine advantage in a cartridge with a limited factory supply.
• Fifty rounds per box, sized for a full practice session rather than a token function check.
• Manufactured to exacting specification so neck tension and overall length stay consistent.

Specifications and their practical meaning

Caliber is .357 Sig, bullet weight is 125 grains, the bullet is the Hornady XTP hollow point, muzzle velocity is 1200 fps, and the box holds 50 rounds. Cases are brass and reloadable. Those numbers define how the cartridge behaves downrange.

Velocity is the entire argument for the Precision One 357 Sig cartridge. Speed flattens trajectory, shortens the time your bullet spends in flight, and helps a hollow point open reliably even through heavy clothing. It also produces sharp muzzle blast, which is simply part of the deal with a bottlenecked pistol round.

Recoil is snappier than a 9mm load of similar bullet weight and the report is sharper, so hearing protection is not optional at an indoor range. Shooters who train with the cartridge regularly adapt to that quickly. The trade you are making is a genuinely flat trajectory and a bullet that arrives fast enough to do its work.

Practical use, storage and reloading the bottleneck case

Feed problems in this chambering almost always trace back to case shoulders and overall length rather than the pistol itself. Factory loaded rounds like these avoid that headache, but it is still worth hand cycling a few from a full magazine to confirm your gun likes them. Then shoot a group at 25 yards and record your zero.

Store the box in a cool, dry place and the powder charge will stay consistent for years. Reloaders should hang onto every case, because Precision One 357 Sig brass is worth more than most straight walled pistol brass and is harder to come by. Watch the case neck for splits after several firings.

Watch your brass supply as closely as your ammunition supply. Because Precision One 357 Sig components are less common than the mainstream chamberings, most owners of these pistols keep a deeper reserve than they would for a 9mm. A few boxes on the shelf means a range trip is never in question.

Stock up while supply is good, and browse the rest of our ammunition selection if you need to top off other calibers in the same order. Specialty chamberings are always the first to disappear when demand spikes.

If you own a pistol in this chambering, buy the ammunition when you see it on the shelf. The Precision One 357 Sig load pairs a serious bullet with serious velocity and comes in a count that encourages practice. This ammunition ships straight to your door wherever state and local law allows.
