Who is the Norma Range & Training .357 Magnum 158gr FN FMJ for?

• Revolver Target Shooters — Needs consistent 357 Magnum handgun ammunition delivering 1,296 fps muzzle velocity and 587–589 ft-lbs of muzzle energy for paper target training at short-to-medium distances from 0 to 50 metres.
• Lever-Action Carbine Shooters — Requires safe feeding in tubular magazines via a flat-nose 158-grain FMJ bullet profile that maintains reliable accuracy on targets up to 100 metres.

Less suitable for: Hunters pursuing game animals, as non-expanding Full Metal Jacket projectiles lack controlled expansion (requiring expanding Jacketed Soft Point or Jacketed Hollow Point hunting ammunition), and shooters using firearms chambered strictly for .38 Special, where .357 Magnum chamber pressures exceed the firearm's rated proof limits.
