Sig Sauer E300A120 Marksman 300 Blackout 125gr OTM Ammo 20rd Box

The Sig Sauer E300A120 Marksman ammunition delivers match-grade accuracy for precision shooting applications in 300 AAC Blackout platforms. This premium load features 125-grain Open Tip Match bullets engineered for consistent ballistic performance at extended ranges. Manufactured to exacting tolerances, each cartridge provides the reliability competitive shooters and tactical professionals demand.

What Makes This Different

Unlike standard ball ammunition, the E300A120 utilizes Open Tip Match projectiles that maintain stability through transonic flight phases. The 125-grain bullet weight optimizes velocity retention while reducing wind drift compared to heavier subsonic loads. Sig Sauer's quality control processes ensure lot-to-lot consistency with velocity variations under 15 fps standard deviation.

Key Features

• 125-grain Open Tip Match bullets for enhanced accuracy and ballistic coefficient
• Brass cases with boxer primers for reliable ignition and reloadability
• Optimized powder charge for consistent velocities around 2,200 fps from 16-inch barrels
• Compatible with all SAAMI-spec 300 AAC Blackout chambers
• Match-grade manufacturing tolerances for competitive shooting applications
• 20 rounds per box, 25 boxes per case (500 total rounds)
• Temperature-stable propellant maintains performance across climate conditions

This ammunition excels in precision rifle competitions where accuracy standards demand sub-MOA performance. The supersonic velocity profile makes it effective for hunting medium game at ranges up to 300 yards. Law enforcement and military users appreciate the consistent terminal performance and barrier penetration capabilities. The brass cases withstand multiple reloading cycles for cost-conscious shooters.
