Let’s Talk About Hornady SST Rifle Bullets, 270 Caliber, .277, 140 Grain
The Hornady SST Rifle Bullets, 270 Caliber, .277, 140 Grain are designed for hunters seeking rapid expansion and deep penetration. Manufactured by Hornady, these bullets combine a polymer tip with a secant ogive and boattail design for enhanced accuracy and ballistic performance. They are a popular choice among .270 Winchester users, known for their consistent performance on a variety of game animals.
My quest for the perfect .270 projectile began years ago, after a frustrating hunt where I wounded a deer with inconsistent ammunition. I needed a bullet that offered flat trajectories for longer shots and reliable expansion to ensure quick, ethical kills. The Hornady SST line seemed to fit the bill, with its reputation for accuracy and terminal performance.
Upon opening the box, I was impressed by the consistent appearance of the bullets. They felt well-made, and the polymer tips were uniformly shaped. Compared to other .270 bullets I’ve used, like the Nosler Ballistic Tip and Sierra GameKing, the SST seemed to have a slightly more aggressive ogive, potentially aiding in long-range accuracy.
My first impression was one of cautious optimism. The sleek design and proven track record of Hornady instilled confidence, but real-world performance would be the ultimate test. I was eager to see how these bullets would perform in my rifle, both on paper and in the field.
Real-World Testing: Putting Hornady SST Rifle Bullets, 270 Caliber, .277, 140 Grain to the Test
First Use Experience
My initial testing of the Hornady SST Rifle Bullets, 270 Caliber, .277, 140 Grain took place at my local shooting range. I handloaded them with a consistent powder charge and seated them to the recommended depth. Conditions were favorable: clear skies and minimal wind.
The .270 Winchester is a flat-shooting cartridge, and the 140-grain SST bullets lived up to that reputation. They grouped impressively tight at 100 yards, producing sub-MOA results with my custom rifle. There were no issues with feeding or extraction.
I noticed a slight increase in muzzle velocity compared to other 140-grain bullets I’ve used. This translated to a flatter trajectory and potentially increased range, something I looked forward to testing in the field. I experienced no surprises or issues during the initial range session.
Extended Use & Reliability
After several months of use, the Hornady SST Rifle Bullets, 270 Caliber, .277, 140 Grain have proven to be remarkably consistent and reliable. I’ve taken them on multiple hunting trips, targeting whitetail deer and antelope in varying conditions. Durability has been commendable; the bullets maintain their shape well during handling and loading.
Cleaning my rifle after using these bullets has been straightforward. I haven’t observed excessive copper fouling in the barrel, indicating a good jacket-to-core bond. Compared to my previous experiences with less consistent bullets, the SST’s performance has been a significant improvement, resulting in cleaner kills and less tracking.
This past fall, I harvested a mule deer at approximately 350 yards with these bullets. The bullet performed exactly as advertised, delivering rapid expansion and a devastating wound channel. This confirmed my belief in the bullet’s terminal performance.
