Lee Load Master Large Primer Feed Attachment 90077 Review

Let’s Dive into Lee Load Master Large Primer Feed Attachment 90077

The Lee Load Master Large Primer Feed Attachment 90077 promises to streamline the priming process on the Lee Load Master progressive press. It aims to eliminate the tedious task of manually feeding primers, offering a faster, more efficient reloading experience.

For years, I’ve struggled with the finicky primer feed on my Lee Load Master. Primers would occasionally flip, jam, or simply not feed, adding significant time and frustration to my reloading sessions. I needed a reliable solution to improve consistency and reduce errors.

Upon unboxing, the Lee Load Master Large Primer Feed Attachment 90077 felt surprisingly lightweight. The plastic construction appeared adequate, though not exceptionally robust. The primer flip tray, with its CAD-designed surface, looked promising for orienting primers correctly.

I considered the RCBS Automatic Priming System and the Hornady Lock-N-Load AP Priming System. However, I chose the Lee option due to its lower price point and seemingly straightforward design, hoping it would offer a good balance of performance and value. The Lee system is also specifically designed for the Load Master press, which was another point in its favor.

Initially, I was cautiously optimistic, hoping the Lee Load Master Large Primer Feed Attachment 90077 would live up to its claims of improved priming efficiency. My biggest concerns were potential issues with primer flipping and consistent feeding.

Real-World Testing: Putting Lee Load Master Large Primer Feed Attachment 90077 to the Test

First Use Experience

I tested the Lee Load Master Large Primer Feed Attachment 90077 at my reloading bench, focusing on loading .45 ACP rounds. The press was setup as normal and I loaded the primer tray with CCI large pistol primers. The conditions were dry and mild, typical for my garage setup.

The initial setup required some fiddling to adjust the primer feed slide to the correct position. Once dialed in, the priming process was noticeably smoother than the original Lee system. The “satisfying click” of the primer feed trigger was indeed present, indicating a primer was properly seated and dispensed.

I experienced a few instances where primers didn’t quite seat flush with the primer pocket. I attribute this to variations in brass case manufacturing tolerances. It’s not necessarily a fault of the Lee Load Master Large Primer Feed Attachment 90077 itself, and was easily addressed by manually ensuring proper seating.

Extended Use & Reliability

After several weeks and loading over 1,000 rounds, the Lee Load Master Large Primer Feed Attachment 90077 has proven to be a worthwhile upgrade. It’s not perfect, but it’s a significant improvement over the stock priming system.

There are no significant signs of wear and tear, although the plastic components do raise some concerns about long-term durability. I expect the primer feed slide to be a wear item in the long run.

Maintenance is relatively simple: occasional cleaning of the primer feed slide and flip tray with a brush and solvent to remove powder residue. So far, it is out performing the original priming system that came with my Lee Load Master progressive press.

Breaking Down the Features of Lee Load Master Large Primer Feed Attachment 90077

Specifications

The Lee Load Master Large Primer Feed Attachment 90077 is designed for use with the Lee Load Master progressive reloading press. It is specifically configured for large primers, both pistol and rifle.

It includes a primer flip tray with a CAD-designed flipping surface. This is designed to orient primers correctly before they enter the feed mechanism. The attachment features a primer feed trigger, which dispenses primers with each pull. It is a lightweight system constructed primarily of durable polymer materials.

These specifications are important because they determine the attachment’s compatibility and intended use. The CAD-designed flip tray should improve the reliability of primer feeding. The primer feed trigger is meant to provide a consistent and controlled priming action.

Performance & Functionality

The Lee Load Master Large Primer Feed Attachment 90077 significantly improves priming consistency compared to the stock Lee priming system. It dramatically reduces primer flipping and misfeeds once properly adjusted.

The primary weakness is the sensitivity of the primer feed slide adjustment: it needs to be precise for reliable operation. The CAD-designed flip tray works better than expected and has significantly reduced flipped primers. Overall, I would say that it meets my expectations.

Design & Ergonomics

The Lee Load Master Large Primer Feed Attachment 90077 is constructed from lightweight plastic, which contributes to its ease of handling. The design is relatively simple, with a focus on functionality over aesthetics.

There is a slight learning curve involved in setting up and adjusting the primer feed slide. However, after a few adjustments, the system becomes easy to use.

Durability & Maintenance

The long-term durability of the plastic components is a concern, especially the primer feed slide. However, with proper care and occasional cleaning, the Lee Load Master Large Primer Feed Attachment 90077 should last for a reasonable amount of time.

Maintenance involves cleaning the primer feed slide and flip tray to remove powder residue. Disassembly for cleaning is straightforward and requires no special tools.

Accessories and Customization Options

The Lee Load Master Large Primer Feed Attachment 90077 does not come with any additional accessories. It is designed as a direct replacement for the stock Lee priming system.

There are no official customization options available from Lee. However, some users have created their own modifications, such as 3D-printed primer guides.
