Sellier & Bellot .357 Magnum 158gr Lead Flat Nose (LFN) ammunition delivers a mild-recoil shooting profile specifically tuned for Western Action disciplines, Single Action Shooting Society (SASS) matches, and paper target training. Designed with an unjacketed 158-grain solid lead projectile, this ammunition achieves a factory-rated muzzle velocity of 343 m/s (1,125 fps) and generates 603 J (445 ft·lbs) of muzzle energy from a 150 mm test barrel. The flat nose profile ensures reliable feeding in lever-action tubular magazines without the risk of primer detonation under recoil, while producing clean, discernible cuts on paper targets.

Key Features

  • Mild Recoil Velocity Profile: Tuned to 343 m/s to reduce felt recoil and accelerate sight recovery between shots compared to full-power hunting rounds.
  • Tubular Magazine Safety: Solid Lead Flat Nose (LFN) geometry prevents nose-to-primer ignition in lever-action rifle magazines.
  • Target Scoring Precision: The unjacketed flat-meplat design punches clean holes in paper targets for straightforward scoring.
  • Reloadable Brass Cases: Loaded into standard non-corrosive, Boxer-primed brass cases suitable for handloading.

Who is the Sellier & Bellot .357 Magnum 158gr LFN Ammunition for?

  • Cowboy Action Competitors — Requires mild recoil and fast sight alignment during timed Single Action Shooting Society stages, supported by this .357 Magnum handgun ammunition's moderate 343 m/s muzzle velocity and 603 J energy output.
  • Recreational Range Shooters — Needs smooth cycling through lever-action rifles and revolvers with minimal fatigue across high-volume range sessions, provided by the 158 grains lead flat nose profile and a 50-round box packaging.

Less suitable for: Dedicated .38 Special-only firearms (which cannot chamber .357 Magnum casings), long-range target shooting beyond 50 metres where trajectory drops 29.9 cm at 100 metres, or medium-game hunting applications where dedicated expanding projectiles such as Jacketed Soft Point (JSP) or Semi-Jacketed Hollow Point (SJHP) cartridges are required.
