First Impressions of Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet

The Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet isn’t just another projectile; it’s a legacy. For decades, the Grand Slam has been synonymous with controlled expansion and deep penetration, a crucial combination for ethically harvesting big game. My first encounter with the Grand Slam series came years ago, hearing seasoned hunters recount tales of one-shot kills on tough game like elk and wild boar.

I needed a reliable bullet for my .270 Winchester that could handle a variety of game, from deer to potentially larger animals like black bear. My usual go-to was a standard boat-tail spitzer, but I was looking for something with more consistent expansion at varying ranges. The Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet promised controlled expansion and high weight retention, features that immediately caught my eye.

Unboxing the 50-count box of Speer Grand Slam .277 130 Grain Soft Point Rifle Bullets, the first thing I noticed was the classic soft-point design. The exposed lead tip was clean and consistent, and the jacket appeared to be well-formed. They felt substantial in hand, a reassuring sign of their robust construction.

Compared to the Hornady InterLock and Nosler Partition, two other popular hunting bullets, the Grand Slam seemed to strike a balance between a bonded core and a traditional cup-and-core design. The InterLock boasts a mechanical interlock between the core and jacket, while the Partition uses a dual-core design for maximum weight retention. The Grand Slam with its internal jacket flutes, seemed to offer a unique compromise.

Initially, I was cautiously optimistic. The Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet had a reputation to live up to. I was eager to see if it could deliver on its promises of accuracy, controlled expansion, and deep penetration.

Real-World Testing: Putting Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet to the Test

First Use Experience

My initial testing of the Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet took place at my local shooting range, preparing for the upcoming deer season. I loaded the bullets into my .270 Winchester and began sighting in at 100 yards. The weather was mild, with a slight breeze, perfect conditions for testing.

The Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet proved surprisingly easy to work up a load for. My rifle consistently produced sub-MOA groups at 100 yards with a moderate powder charge. The accuracy was immediately impressive.

There were no immediate issues, but I did notice that the bullets were slightly more sensitive to seating depth than my usual target rounds. Small adjustments made a noticeable difference in group size. This wasn’t a problem, but something to keep in mind during reloading.

Extended Use & Reliability

After several months of using the Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet at the range and in the field, I’m confident in its reliability. I took it on several whitetail hunts in varying conditions, from crisp, dry mornings to damp, snowy afternoons. The bullets performed consistently in each scenario.

Durability wise, the bullets hold up well during reloading and transportation. I experienced no deformation or damage to the soft points, even after repeated handling. Cleaning my rifle after firing these bullets was no different than with other copper-jacketed projectiles.

Compared to my previous experiences with standard soft-point bullets that sometimes fragmented excessively, the Speer Grand Slam .277 130 Grain Soft Point Rifle Bullet offers noticeably improved performance. The recovered bullets showed consistent expansion and excellent weight retention. It outperformed my expectations.
