Allstar/Magnus Bullets .45 Colt .452" 255 gr SWCBB 400/Box
$68.49
If you reload .45 Colt ammunition, Magnus Bullets offers cast .452" diameter bullets in 255-grain Semi-Wadcutter Beveled Base (SWCBB) configuration—a classic profile built for reliable feeding and consistent performance in revolvers and lever-action rifles. These bullets are engineered from a proprietary alloy blend designed to balance hardness with durability: tough enough to handle velocity without excessive leading, yet capable of taking impact without shattering on steel targets. That balance makes them practical for range sessions, cowboy action shooting, and hunting where you need dependable, affordable projectiles without the premium price tag of jacketed rounds.
Magnus Bullets manufactures these projectiles using modern casting machinery and virgin alloys—no recycled scrap. The specific alloy composition (91% lead, 4% tin, 5% antimony) has been formulated to perform at handgun velocities typical of .45 Colt loads without leading your bore excessively. That means less cleanup and more time shooting. The SWCBB profile is a proven design: the semi-wadcutter shape provides clean holes for target scoring, while the beveled base promotes smooth chambering and consistent seating.
This box contains 400 projectiles, giving you plenty of supply for a serious reloading session or to stock your bench for ongoing practice and competition. Whether you're working up loads for a Colt SAA, a modern revolver, or a Marlin lever gun, these bullets are a straightforward, no-frills component built to shoot and perform.

Frequently Asked Questions
Will these bullets work in my .45 Colt revolver?
Yes. The .452" diameter and SWCBB profile are standard for .45 Colt applications, whether you're loading for a traditional single-action revolver, modern double-action revolver, or lever-action rifle chambered in .45 Colt.
What velocity should I load these to?
These bullets are designed to handle handgun velocities typical of .45 Colt loads—the alloy hardness is formulated to minimize leading at speeds around 1200 FPS and below, which covers the typical range for most .45 Colt reloads. Consult published reloading data for your specific powder and case to stay safe and accurate.
Will they lead my barrel?
The alloy blend is hardened specifically to reduce leading during normal shooting, though the degree depends on your specific load, firearm, and barrel condition. The formulation is designed to perform with little or no leading in most handguns when loaded at appropriate velocities.
Can I use these on steel targets?
Yes. Unlike softer cast bullets, these are formulated not to shatter when striking steel, making them suitable for practice on reactive targets without the risk of dangerous fragmentation.
