Hornady 308/155-178 A-Max Custom Seating Stems Review

Let’s Dive into Hornady 308/155-178 A-Max Custom Seating Stems

The Hornady 308/155-178 A-Max Custom Seating Stems are a specialized reloading tool designed to enhance the precision and consistency of bullet seating when using Hornady’s A-Max projectiles in .308 Winchester cartridges. This seemingly simple piece of kit can have a significant impact on the final accuracy and overall performance of handloaded ammunition. Let’s explore what makes these seating stems a potentially valuable addition to any serious reloader’s bench.

My journey to acquiring these seating stems started with a persistent problem: inconsistent seating depths with my handloads. I was chasing that elusive sub-MOA performance from my precision rifle, and minor variations in seating depth were proving to be a significant obstacle. I was looking for a solution that could minimize bullet deformation and ensure consistent contact between the seating stem and the bullet ogive.

Unboxing the Hornady 308/155-178 A-Max Custom Seating Stems revealed a small, precisely machined piece of metal. The initial impression was one of solid build quality, the stem felt durable. The stem looked like it could withstand repeated use without degradation.

Compared to universal seating stems, the Hornady A-Max stems offer a specifically tailored fit for the unique profile of A-Max bullets. The generic stems often leave a ring mark on the bullet tip. This can lead to inconsistent ballistic coefficients, and ultimately, reduced accuracy. I chose the Hornady stems because I wanted to eliminate any potential for bullet deformation during the seating process.

My first impression was one of cautious optimism. I was eager to see if these stems could truly make a difference in the consistency and accuracy of my handloads. I hoped that the Hornady custom fit would translate into tighter groups downrange.


Real-World Testing: Putting Hornady 308/155-178 A-Max Custom Seating Stems to the Test

First Use Experience

I tested the Hornady 308/155-178 A-Max Custom Seating Stems at my local shooting range, focusing on precision rifle shooting at 100 and 200 yards. I meticulously loaded a batch of .308 Winchester cartridges with 168-grain A-Max bullets. I used the new seating stems, carefully recording seating depths and overall cartridge lengths (COAL).

The weather conditions were mild, with a slight crosswind that tested the consistency of my handloads. The custom seating stem felt smoother and more consistent than my generic seating stem. I immediately noticed less resistance during the seating process.

The ease of use was apparent right away. The Hornady seating stems fit perfectly into my Hornady seating die. It required no modifications or adjustments.

My initial results were promising. I achieved slightly tighter groups compared to loads seated with my standard seating stem. The difference wasn’t dramatic, but it was noticeable and encouraging.

Extended Use & Reliability

After several months of consistent use, the Hornady 308/155-178 A-Max Custom Seating Stems have proven to be a reliable addition to my reloading bench. The stems show no signs of wear and tear despite seating thousands of bullets. The stems look like they will last for many years to come.

Durability has been excellent. The Hornady stems are made from high-quality materials. The stems hold their shape even under the pressures of repeated bullet seating.

Maintenance is simple. I wipe the stem clean with a dry cloth after each reloading session. This keeps it free from powder residue and ensures smooth operation.

Compared to my previous experiences with universal seating stems, the Hornady A-Max stems consistently produce more uniform seating depths. The results translate into improved accuracy on the range. They have become an indispensable part of my precision reloading process.
