Magnus Bullets .45 Colt .452in 255 gr SWCBB Review

Unboxing & First Thoughts on the Magnus Bullets .45 Colt .452in 255 gr SWCBB

For years, I’ve relied on a consistent supply of quality projectiles for my handloading endeavors, and recently, a specific need arose for accurate, dependable lead bullets for my .45 Colt handguns. I’d heard good things about Magnus Bullets, and their .45 Colt .452in 255 gr SWCBB offering caught my eye due to its specifications and promising alloy composition. My previous batch of cast bullets from a lesser-known supplier had been inconsistent, leading to frustrating range sessions and the occasional performance hiccup, so a reliable source was paramount. Upon receiving the box, my initial impression was one of solid manufacturing. The bullets themselves felt substantial, uniform in shape, and bore a clean, well-defined heel. Compared to some bulk options I’ve encountered, these offered a noticeable step up in presentation. It wasn’t an overwhelming sense of awe, but rather a quiet satisfaction knowing I held a product that appeared to be made with care and precision.

Real-World Testing: Putting Magnus Bullets .45 Colt .452in 255 gr SWCBB to the Test

First Use Experience

My primary testing ground for these Magnus Bullets was my personal reloading bench and then, inevitably, the firing line at my local outdoor range. I meticulously loaded them into Starline brass, using a standard set of load data for 255-grain lead bullets in .45 Colt. The testing focused on accuracy at 25 and 50 yards, as well as observing any signs of leading in my revolvers.

Conditions varied from cool mornings to warmer afternoons, and while I avoided any extreme weather, I did subject them to repeated firing sessions over several outings. The ease of use was immediately apparent; they dropped cleanly from my sizing die and seated into the brass without issue. My only initial surprise was the consistent fit, which is a welcome change from bullets that require significant manipulation.

Extended Use & Reliability

After several hundred rounds downrange, these Magnus Bullets continue to impress. They’ve become my go-to for most of my .45 Colt reloading. I’ve experienced remarkably little leading, even in firearms that have historically been prone to it with softer bullets.

Durability has been excellent; there are no visible signs of cracks or premature deformation, even when pushed near their advertised velocity limits. Maintenance has been straightforward, primarily involving standard bore cleaning after each range visit. Compared to some budget options that would develop significant fouling after just a few cylinders, these cast bullets offer a far more forgiving shooting experience.

Breaking Down the Features of Magnus Bullets .45 Colt .452in 255 gr SWCBB

Specifications

The Magnus Bullets .45 Colt .452in 255 gr SWCBB are precisely engineered for performance and reliability. They feature a .452in diameter, ensuring a snug fit in most .45 Colt barrels, which is crucial for accuracy and minimizing gas blow-by. The 255 grain weight provides a substantial projectile, ideal for applications where momentum and impact are key considerations.

Their construction utilizes a proprietary alloy mix of 91% lead, 4% tin, and 5% antimony. This specific blend is engineered for hardness, allowing them to be fired at velocities up to 1200 FPS with minimal risk of barrel leading. This alloy is also designed to prevent shattering on impact with steel targets, offering a safer shooting experience.

The Semi Wadcutter Bevel Base (SWCBB) design offers distinct advantages. The flat nose of the semi-wadcutter creates a clean-cutting meplat, resulting in distinct, easy-to-read bullet holes on paper targets, which aids in accuracy assessment. The bevel base is a practical feature, simplifying the seating process during reloading and reducing the risk of damaging the bullet base. This pack quantity of 400 Bullets is also a thoughtful offering, striking a good balance between bulk purchasing and manageable storage for most handloaders.

Performance & Functionality

In practice, the Magnus Bullets .45 Colt .452in 255 gr SWCBB perform exceptionally well in their intended role. Their primary function is to be a reliable projectile for handloaded .45 Colt ammunition, and they excel at this. Accuracy is a standout feature; when loaded with appropriate powders and charges, these bullets consistently group tightly, both from a bench rest and from a standing position.

The 255 gr SWCBB projectile’s flat nose creates clean holes, making target analysis straightforward. The .452in diameter ensures a good bore seal, contributing to consistent velocity and minimal gas leakage. The ability to handle velocities up to 1200 FPS without significant leading is a testament to the quality of the Magnus alloy. This allows for flexibility in load development, catering to both moderate plinking rounds and more spirited target loads.

Design & Ergonomics

The SWCBB (Semi Wadcutter Bevel Base) design of these Magnus Bullets is a practical consideration that significantly impacts their usability. The semi-wadcutter profile is not just for aesthetics; it creates a distinct shoulder that produces clean-edged holes in paper targets, making it easier to read your shot placements. This geometric feature is a boon for anyone focused on improving their marksmanship.

The bevel base is another thoughtful design element, smoothing the transition of the bullet into the casing during the reloading process. This minimizes the chance of damaging the bullet’s base or deforming it during seating, which is a common frustration with some other cast bullet designs. The overall finish of the bullets is consistent and smooth, indicating good mold quality and manufacturing control.

Durability & Maintenance

The durability of these projectiles is directly tied to their alloy composition and the manufacturing process. The 91% lead, 4% tin, and 5% antimony blend is engineered for resilience. Firing them at velocities approaching 1200 FPS has shown no adverse effects, such as excessive wear or deformation of the bullet’s base or sides.

Maintenance is primarily related to the firearm itself, rather than the bullets. The stated benefit of minimal leading means less frequent and less intensive barrel cleaning is required. After extended shooting sessions, a standard bore brush and solvent are usually sufficient to restore the barrel to a clean state. This contrasts sharply with softer lead bullets that can leave significant fouling requiring more rigorous cleaning.

Accessories and Customization Options

As a component rather than a finished product, these Magnus Bullets don’t come with traditional accessories. However, their primary “accessory” is the potential they unlock for handloaders. The .452in diameter means they are well-suited for use with standard .45 Colt reloading dies, and the SWCBB design integrates seamlessly into typical reloading procedures.

Their compatibility extends to various propellant types and load data. Experienced handloaders can experiment with different powders to achieve specific velocity and pressure profiles, all while leveraging the inherent consistency of these projectiles. The 400 Bullet quantity also means that a single purchase can support multiple reloading sessions, allowing for sustained testing and load refinement without frequent reordering.

Pros and Cons of Magnus Bullets .45 Colt .452in 255 gr SWCBB

Who Should Buy Magnus Bullets .45 Colt .452in 255 gr SWCBB?

These Magnus Bullets .45 Colt .452in 255 gr SWCBB are an excellent choice for experienced handloaders who specialize in the .45 Colt cartridge.
