Let’s Dive into Speer Grand Slam .308 165 Grain Soft Point Rifle Bullet
The Speer Grand Slam .308 165 Grain Soft Point Rifle Bullet is designed for hunters seeking deep penetration and controlled expansion on large game. These bullets are a legacy of Speer’s commitment to providing reliable and accurate hunting ammunition, focusing on weight retention and consistent performance.
My quest for the ideal .308 bullet stemmed from persistent issues with inconsistent expansion and penetration on elk hunts in the rugged backcountry of Montana. I needed a bullet that could reliably perform at varying distances, delivering a quick, ethical kill even on tough, mature bulls.
The Speer Grand Slam bullets arrived in a simple, functional box of 50. My initial impression was that these were no-nonsense hunting bullets, built for performance rather than aesthetics. The soft point was well-formed, and the jacket appeared robust, suggesting good weight retention.
Compared to the Hornady InterLock and Nosler Partition, the Speer Grand Slam stood out due to its advertised internal jacket flutes, designed for consistent expansion. I chose the Grand Slam hoping these features would translate to more reliable performance on game, ultimately providing better results than other common options. My first impressions were positive. It felt like this bullet could meet my accuracy and penetration needs for the upcoming hunting season.
Real-World Testing: Putting Speer Grand Slam .308 165 Grain Soft Point Rifle Bullet to the Test
First Use Experience
I initially tested the Speer Grand Slam .308 165 Grain Soft Point Rifle Bullet at my local shooting range, zeroing my custom-built .308 bolt-action rifle. The range offered distances up to 300 yards, allowing me to assess the bullet’s accuracy and trajectory.
Conditions were varied during testing, ranging from calm, sunny days to gusty afternoons with light rain. Accuracy remained consistent, hovering around 1 MOA (Minute of Angle) when fired from a stable rest, even with the changing wind. Getting used to the bullet’s trajectory took a bit of time, as it differed slightly from my previous loads.
After my first range session, I had no major issues with the Speer Grand Slam. I achieved good accuracy and consistent velocities, which instilled confidence for its use during a hunt.
Extended Use & Reliability
After several months of use, including extensive range sessions and load development, the Speer Grand Slam bullets have proven to be remarkably consistent. There have been no signs of degradation or change in performance after loading and storing these bullets.
The bullets held up well, exhibiting no signs of deformation or jacket separation during the loading process. Cleaning was straightforward, with minimal copper fouling in the barrel after extended shooting sessions. This outperforms some cheaper bullets I’ve used, which tend to leave heavy copper deposits.
Compared to my previous experiences with other hunting bullets, the Speer Grand Slam stands out for its reliable expansion and deep penetration. It performs as advertised.
