Let’s Dive into LEE 90772 COLLET DIE 300 AAC DIE SET
The LEE 90772 COLLET DIE 300 AAC DIE SET offers reloaders a unique approach to neck sizing, promising improved accuracy and reduced runout. Manufactured by Lee Precision, a name synonymous with affordable and innovative reloading equipment, this die set aims to deliver precision without breaking the bank. This isn’t just another die set; it’s a gateway to potentially squeezing even tighter groups from your .300 AAC Blackout rifle.
I’ve been reloading for over a decade, always chasing that elusive perfect round. My problem was consistent neck tension and minimizing runout, crucial for accuracy at longer distances. I was seeking a cost-effective way to improve my reloading process without investing in expensive, specialized equipment.
Upon unboxing, the LEE 90772 COLLET DIE 300 AAC DIE SET feels robust and well-machined, albeit with Lee’s characteristic no-frills finish. The steel components inspire confidence, and the design seems straightforward, promising ease of use. It’s lightweight, easy to handle, and the included shell holder and powder dipper are a welcome bonus, especially for beginners.
Compared to a standard full-length resizing die set from RCBS and a Redding neck sizing die, the Lee collet die set offered a different approach. I chose the LEE 90772 COLLET DIE 300 AAC DIE SET because of its collet design, which promised to squeeze the neck against a mandrel, resulting in a perfectly aligned case neck and reduced runout. The other options resize the entire case or rely on bushing systems, both of which can be more expensive and potentially less precise for neck tension consistency.
My first impression was cautiously optimistic. While the finish wasn’t as polished as some higher-end die sets, the design intrigued me, and the price point was definitely appealing. I was excited to see if the collet design could live up to its promise of improved accuracy and reduced runout without requiring significant adjustments to my reloading process.
Real-World Testing: Putting LEE 90772 COLLET DIE 300 AAC DIE SET to the Test
First Use Experience
I tested the LEE 90772 COLLET DIE 300 AAC DIE SET at my local shooting range, focusing on reloading .300 AAC Blackout rounds for my AR-15 pistol. The range offered a controlled environment for load development and accuracy testing. I worked up loads using a consistent powder charge and bullet seating depth, using the rounds I reloaded with the Lee dies.
The performance was consistent, even in the dusty environment of the range. The collet die consistently sized the case necks. I did have to ensure my cases were well-lubricated, which helped reduce friction and ensure smooth operation.
The LEE 90772 COLLET DIE 300 AAC DIE SET was relatively easy to use, although it did require some initial adjustments to the die depth to achieve the desired neck tension. Once the die was properly adjusted, the process became smooth and repeatable. It took about 10-15 minutes of tinkering before I was consistently producing properly sized cases.
The biggest surprise was the reduced runout I observed compared to cases resized with my full-length die. Initial testing showed a noticeable improvement in bullet seating consistency as well.
Extended Use & Reliability
After several months of using the LEE 90772 COLLET DIE 300 AAC DIE SET, it has proven to be a reliable and consistent tool. The die shows no signs of wear and tear, despite frequent use. The finish has held up well, and the internal components remain smooth and functional.
Durability has been impressive; the die body is solid, and the collet mechanism seems well-engineered to withstand repeated use. Regular cleaning with a brush and solvent is all it takes to keep the LEE 90772 COLLET DIE 300 AAC DIE SET functioning optimally. A light application of case lube inside the die body further ensures smooth operation.
Compared to my previous experience with full-length resizing dies, the LEE 90772 COLLET DIE 300 AAC DIE SET consistently produces more accurate and consistent ammunition. The reduced runout translates to tighter groupings on the target.
