Sierra 8360 Sports Master .357 Cal 158 gr JHC Ammo - 100 Rounds/Box

Sierra's 8360 Sports Master .357 Cal 158 gr JHC bullets are engineered for handloaders who want reliable, consistent performance downrange. Built for .357 Magnum and .357 Sig reloading, these 158-grain jacketed hollow cavity rounds deliver the kind of terminal performance that matters in hunting and defensive applications. Whether you're loading for a revolver or semi-auto, Sierra's reputation for quality and attention to detail means you can focus on your loads instead of worrying about bullet inconsistencies.

The serrated power jacket design is the standout here—those serrations control expansion along predictable lines when the bullet hits its mark, promoting uniform mushrooming and maximum energy transfer. This engineering pays off across a wide velocity range, so your loads perform reliably whether you're running mild plinking loads or full-house magnum speeds. You get 100 rounds per box, packaged in quantities that work for serious reloaders and shooters who demand consistency between batches.

Sierra backs these bullets with quality guarantees on both materials and workmanship, so you're not gambling on QC. If you're building .357 loads for hunting, target work, or self-defense, the Sports Master line gives you a no-nonsense bullet that does what it's supposed to do.
