Can I use this S&B 158 Grain LFN ammunition in firearms with polygonal bore profiles?

No, it is recommended to avoid using unjacketed lead flat nose rounds in handguns with polygonal bore profiles due to the potential for rapid lead buildup. For those specific firearms, fully jacketed ammunition should be selected instead.

What kind of drop can I expect from the S&B 357 Magnum 158 Grain LFN at longer distances out of a 6-inch barrel?

Out of a standard 6-inch test barrel, this ammunition features a muzzle velocity of 1,125 fps and maintains a zero drop at 25 yards. At 50 yards, you will experience approximately a 1.2-inch drop while retaining 1,068 fps, and at 100 yards, the drop increases to about 10.0 inches.

Are the brass cases of the S&B 357 Magnum V311882 suitable for reloading?

Yes, these cartridges feature factory reloadable brass cases paired with non-corrosive Boxer primers. This makes them an economical choice for handgun owners who prefer to reload their own Boxer-primed brass after range sessions.

What licensing requirements apply when purchasing this ammunition in Australia?

Because this is regulated chemical propellant ammunition, acquiring it in Australia requires a valid state or territory firearms licence with the appropriate calibre entitlement, such as a Category H licence for handguns or Category A/B for lever-action rifles. Dealers must verify your registration and permit details before any sale or delivery can be completed.

The Sellier & Bellot .357 Magnum 158 Grain LFN ammunition provides consistent, economical performance for target practice, competition, and recreational shooting. Loaded with an unjacketed 158-grain Lead Flat Nose (LFN) projectile, this factory ammunition generates a muzzle velocity of 1,125 fps (343 m/s) and a muzzle energy of 444 ft-lb (603 J) from a standard 150 mm (6-inch) test barrel. Built with reloadable brass cases and non-corrosive Boxer primers, it offers clean paper punching and reliable feeding across both revolvers and tubular-magazine carbines chambered for .357 Magnum.
