SIG SAUER Elite Copper .300 Win Mag 165-Grain Hunting Ammo

SIG SAUER .300 Winchester Magnum 165 Grain Elite Copper Hunting Ammunition

SIG SAUER Elite Copper Hunting ammunition combines the power and reach of .300 Winchester Magnum with a 165-grain solid-copper hunting projectile. Designed for hunters who want reliable factory ammunition with controlled expansion and dependable feeding, this load uses premium components, an optimized bullet profile, and nickel-plated cartridge cases. Each box contains 20 centerfire rifle cartridges.

The 165-grain bullet weight gives .300 Winchester Magnum hunters a versatile balance of speed, trajectory, and terminal performance. It is suitable for a range of medium- and large-game applications when used within the shooter’s ability, the ammunition’s performance envelope, and local hunting regulations. The rifle, barrel length, environmental conditions, and individual lot can all affect velocity and point of impact, so field preparation should include testing from the actual firearm.

Solid-Copper Hunting Projectile

The Elite Copper projectile is made from solid copper rather than using a conventional lead core. Its hunting-oriented nose geometry is engineered to promote expansion while supporting smooth feeding in the rifle. SIG SAUER states that the design can produce expansion up to approximately 1.8 times the original bullet diameter, helping create a wider wound channel while the one-piece construction supports penetration and weight retention.

Solid-copper bullets are often longer than lead-core bullets of the same weight because copper is less dense than lead. That makes consistent bullet construction, cartridge geometry, and rifle compatibility especially important. SIG SAUER developed this factory load as a complete system rather than leaving the shooter to match a projectile with a handload.

Premium Cases, Primers, and Propellant

SIG SAUER describes its Elite Copper ammunition as loaded with premium-quality powders and primers selected to minimize velocity variation. Lower shot-to-shot variation supports a more predictable trajectory and helps the shooter build dependable data for a hunting rifle. The nickel-plated cases provide a smooth, corrosion-resistant exterior and can make chamber checks and cartridge inspection easier in changing field conditions.

Reliable feeding also matters when a follow-up shot may be needed. The projectile’s optimized nose geometry and the finished cartridge dimensions are intended to support proper cycling and chambering in compatible .300 Winchester Magnum rifles. As with any hunting ammunition, users should test the load before the season rather than assuming that every rifle will produce the same accuracy or point of impact.

Why Hunters Choose This Load

• 165-grain solid-copper projectile: A versatile bullet weight with one-piece copper construction.
• Controlled expansion: Engineered to expand while maintaining the structural integrity needed for penetration.
• Optimized feeding profile: Designed to chamber smoothly in compatible hunting rifles.
• Premium loading components: Quality powder and primers help limit unnecessary velocity variation.
• Nickel-plated cases: Provide a smooth, corrosion-resistant surface for dependable field use.
• Twenty-round box: Supports initial zeroing, trajectory confirmation, hunting use, and later zero checks with the same load.

Confirm the Exact Ammunition

This listing is for SIG SAUER manufacturer part number E3WMH120, corresponding to factory SKU E3WMH1-20 and UPC 798681576760. It is loaded in .300 Winchester Magnum with a 165-grain Elite Series solid-copper hunting projectile and packaged 20 rounds per box.

Only use this ammunition in a firearm specifically marked for .300 Winchester Magnum. It is not interchangeable with .300 Winchester Short Magnum, .300 Weatherby Magnum, .300 PRC, .308 Winchester, or other .30-caliber cartridges. Confirm the chamber marking on the rifle and the cartridge designation on the ammunition before loading.

Range Confirmation and Field Preparation

Before hunting, confirm reliable feeding, extraction, and accuracy from the rifle that will be carried. Establish a zero at a known distance and verify impact at the ranges expected in the field. A chronograph can help document actual muzzle velocity, but trajectory should still be checked against real impacts because sight height, atmospheric conditions, and rifle setup influence the result.

Store ammunition in a cool, dry location away from excess heat, moisture, oils, and solvents. Inspect cartridges before use and keep them secured from unauthorized users. Follow the firearm manufacturer’s instructions, observe applicable hunting rules, and wear appropriate eye and hearing protection whenever shooting.
