Overview
The Magnum Research .429 DE 240gr Jacketed Hollow Point (JHP) ammunition is precision-engineered to deliver consistent performance and reliable function specifically in firearms chambered for the .429 DE cartridge, predominantly the Desert Eagle platform. This ammunition is developed to meet the demanding specifications of large-caliber semi-automatic pistols, providing optimal energy transfer and controlled expansion.
Key Features
Precision Projectile Construction
Each 240-grain Jacketed Hollow Point projectile is manufactured with a robust copper jacket over a lead alloy core. This construction facilitates controlled expansion upon impact, mitigating over-penetration while ensuring maximum energy transfer to the target. Consistent jacket thickness and a precisely formed hollow point cavity are integrated to guarantee uniform ballistic performance across the production lot, critical for repeatable accuracy.
Optimized Propellant Load
This ammunition incorporates a meticulously measured propellant charge formulated to achieve consistent velocities and pressures within the .429 DE operating parameters. The optimized powder burn rate contributes to reliable cycling in gas-operated systems, reducing residue buildup and mitigating variability in shot-to-shot performance, which is essential for both accuracy and system longevity.
Reliability and Feed Integration
Magnum Research .429 DE cartridges are manufactured to strict SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) specifications. This adherence ensures uniform case dimensions, primer seating depth, and cartridge overall length (COAL), optimizing feeding and extraction cycles in high-capacity, heavy-recoiling semi-automatic handguns. The cartridge design prioritizes reliable magazine integration and chambering under diverse operating conditions.
