SIG SAUER Elite Match Grade .300 Win Mag 190-Grain OTM Ammo

Description

SIG SAUER Elite Match Grade .300 Winchester Magnum 190-grain OTM ammunition is built for precision rifle shooting, long-range practice, and competition. This exact 20-round load is identified by UPC 798681552955 and SIG SAUER catalog number E3WMM1-20, represented in the store’s protected manufacturer field as E3WMM120. It combines a 190-grain open-tip match projectile with a brass case and match-oriented quality controls.

Heavy-for-caliber match projectile

The 190-grain open-tip match bullet gives .300 Winchester Magnum shooters a high-mass projectile suited to precision work at extended distances. An OTM bullet is produced with a small opening at the nose as a result of the manufacturing process used to form a uniform jacket and consistent core. It should not be confused with a conventional expanding hollow-point hunting or defensive bullet; the design priority is accuracy and aerodynamic consistency.

Exact-variant sources list a muzzle velocity of approximately 2,850 feet per second. Published velocity is a reference figure rather than a guarantee. Actual results vary with barrel length, chamber dimensions, temperature, elevation, ammunition lot, and chronograph setup.

Elite Match Grade construction

SIG SAUER manufactures its match rifle ammunition to support consistent ignition, geometry, and ballistic performance. The cartridge uses a brass case and premium primer, with production monitoring intended to identify dimensional variation. Consistent cartridge construction matters in precision shooting because small differences in seating, concentricity, ignition, or velocity can become more visible as distance increases.

For precision rifles and long-range evaluation

This load is intended for rifles chambered specifically for .300 Winchester Magnum. Before selecting it for a match or long-range session, confirm reliable chambering, practical accuracy, and point of impact in the intended rifle. Barrel twist, chamber, throat, muzzle device, optic setup, and environmental conditions all influence downrange results. A shooter should build verified dope from actual range data rather than relying only on published velocity.

Safe storage and use

• Use only in a firearm clearly marked and chambered for .300 Winchester Magnum.
• Follow the rifle manufacturer’s instructions and all standard ammunition-safety practices.
• Inspect each cartridge before loading and do not use ammunition showing corrosion, deformation, bullet setback, or other damage.
• Store ammunition in a cool, dry location protected from moisture, extreme heat, and unauthorized access.
• Confirm the range’s rules regarding magnetic projectiles, target placement, and high-energy rifle cartridges.

This listing contains one 20-round box. It does not include a rifle, magazine, optic, or storage case. For .300 Winchester Magnum shooters seeking a factory SIG SAUER match load with a 190-grain OTM projectile, E3WMM1-20 provides a clearly documented option for precision training and competition.
