First Impressions of HSM Ammunition .303 British 150 Grain Sierra Spire Point Rifle Ammunition HSM-303BRIT-5-N $5.00 Off
The .303 British cartridge. It’s a classic, steeped in history, and still kicking in rifles around the world. When I saw the HSM Ammunition .303 British 150 Grain Sierra Spire Point Rifle Ammunition HSM-303BRIT-5-N $5.00 Off on offer, I was immediately intrigued, hoping to find a reliable and accurate factory load for my trusty Lee-Enfield.
I’ve been reloading .303 British for years, chasing that perfect combination of accuracy and terminal performance. However, the convenience of factory ammo is undeniable, especially when time is short or components are scarce. I was seeking a factory option that could deliver consistent results for both range practice and, potentially, deer hunting.
The ammo arrived in a simple, no-frills box. The brass looked clean and the Sierra Spire Point bullets were seated consistently. Compared to some other budget .303 offerings I’ve seen, the HSM ammo immediately presented a more professional appearance.
I’ve used PPU (Prvi Partizan) .303 in the past, which is generally affordable, and also some older Winchester Super-X. The HSM seemed a step up in quality from the PPU, with a more consistent bullet profile, and I was hoping it would perform better than the older Winchester in terms of accuracy. I ultimately chose the HSM due to the Sierra bullet and HSM’s reputation for quality control.
My first impression was cautiously optimistic. The ammo looked good, and I was eager to see how it performed downrange. I hoped that the Sierra Spire Point would deliver accuracy comparable to my handloads, while the HSM manufacturing would provide consistent performance.

First Use Experience
I tested the HSM Ammunition .303 British 150 Grain Sierra Spire Point Rifle Ammunition at my local range, using my well-worn Lee-Enfield No. 4 Mk I*. The range offers distances out to 200 yards, allowing for a decent assessment of accuracy and consistency. The weather was typical for the Pacific Northwest: slightly overcast with a light drizzle.
Initially, I was impressed with the consistency of the ammunition. There were no noticeable hangfires or misfeeds, and the recoil felt predictable. My first five-shot group at 100 yards, using iron sights, measured around 3 inches.
I didn’t encounter any immediate issues, although the rifle did seem to require a bit more cleaning than when using my handloads. There were no alarming pressure signs on the spent cases. The slightly increased fouling was the only minor surprise.
Extended Use & Reliability
After several range sessions and approximately 200 rounds fired, the HSM Ammunition has proven to be reasonably reliable. I’ve experienced no failures to feed, fire, or eject. There hasn’t been a single dud round in all the boxes I’ve tested.
The brass cases show no signs of excessive stretching or other pressure-related issues, indicating safe loading pressures. There is some noticeable fouling after extended shooting, requiring more frequent cleaning to maintain optimal accuracy. The ammunition continues to provide consistent velocities and acceptable accuracy for my purposes.
Compared to my handloads, the HSM doesn’t quite match the pinpoint accuracy I can achieve with carefully selected components and tailored loads. However, the HSM Ammunition offers a significant improvement over some of the cheaper, mass-produced .303 options on the market and is a good choice when I don’t have the time to reload. It’s a compromise between ultimate precision and convenience.

The ammunition comes in boxes of 20 rounds, a standard quantity for rifle ammunition. The cases are made of brass, suitable for reloading. The primers are centerfire, ensuring reliable ignition.
The 150-grain bullet weight is a good compromise for the .303 British, offering a balance of velocity and energy. The Sierra Spire Point design is intended for hunting, providing controlled expansion for effective terminal performance on medium-sized game. The brass cases are essential for reloaders, allowing for cost-effective practice and load development.

Functionally, it feeds reliably in my Lee-Enfield rifle and the recoil is manageable.
The strengths lie in its consistency and reliable feeding. The ammunition delivers predictable velocities and decent accuracy, shot after shot. The main area for potential improvement would be tightening up the accuracy to rival custom handloads; however, that would likely increase the price point.
