Allstar/Magnus Bullets .40/10mm .401" 180 gr FPBB 500/Box

Magnus Bullet Co. Allstar/Magnus .40/10mm .401" 180 Grain FPBB (Full Profile Bullet Box) cast bullets deliver precision and reliability for handloaders and shooters who demand consistent performance. Manufactured from virgin alloys engineered to exacting standards, these 500-round bulk packages support high-volume training, competition reloading, and duty ammunition production for both .40 S&W and 10mm platforms.

The proprietary alloy composition—91% lead, 4% tin, and 5% antimony—balances hardness and integrity across a wide velocity envelope. This metallurgical approach allows safe firing velocities up to 1,200 feet per second with minimal leading in most handguns, while the bullet construction resists fragmentation and shattering when contacting steel targets downrange. The .401" diameter and 180-grain weight profile work across standard .40 S&W and 10mm chambers with minimal sizing requirements, reducing prep time during the reloading cycle.

Serious reloaders—law enforcement personnel assembling duty loads, competitive shooters managing round count costs, and range trainers burning through high-volume practice sessions—depend on Magnus cast bullets for economical, repeatable ammunition production. The 500-round box format streamlines inventory management and cost-per-round calculations for users maintaining multiple calibers or building loads for departmental standards and match specifications.

Cast bullet ammunition represents a proven alternative to jacketed factory rounds, offering significant savings without sacrificing accuracy or terminal performance in target and training applications. The Magnus .40/10mm lineup addresses the heavy-caliber defensive segment, where shooters prioritize cost efficiency alongside functional reliability.
