One Month Later: Barnes Bullets 30412 TSX 338 Caliber .338 225 GR TSX Flat Base 50 Box Review
The Barnes Bullets 30412 TSX 338 Caliber .338 225 GR TSX Flat Base 50 Box represents a commitment to accuracy and ethical hunting. These bullets, manufactured by Barnes, are designed for deep penetration and consistent expansion, promising a quick and humane kill. The all-copper construction and the Triple-Shock X (TSX) design have made them a favorite among serious hunters, particularly those pursuing large or dangerous game. I was eager to see if they lived up to their reputation and if the hype was justified for the price.
My journey to these bullets started with a persistent problem: inconsistent performance with lead-core bullets on tough game. I was hunting elk in Colorado, and I experienced two instances where my shots, while seemingly well-placed, did not result in immediate stops. The search for a bullet that offers both devastating terminal performance and reliable penetration led me to the Barnes TSX. I was looking for a bullet that would perform consistently, regardless of the angle or intervening brush.
The unboxing experience was straightforward: a simple, functional box containing 50 gleaming copper bullets. Immediately, the precision of the manufacturing was apparent. The weight consistency, evident even just by feel, was very promising. They felt solid, well-made, and ready for serious work.
I considered Nosler AccuBond and Federal Trophy Bonded Tip as alternatives. However, the all-copper, lead-free design of the Barnes TSX and its reputation for 100% weight retention ultimately swayed my decision. I wanted to minimize lead exposure and ensure maximum energy transfer upon impact. The TSX offered a unique combination of features that the others couldn’t match.
My first impression was excitement mixed with cautious optimism. The Barnes name carries weight, but I knew that real-world performance is what truly matters. I was eager to see if these bullets could deliver on their promises of accuracy, penetration, and humane kills.
Real-World Testing: Putting Barnes Bullets 30412 TSX 338 Caliber .338 225 GR TSX Flat Base 50 Box to the Test
First Use Experience
My initial testing ground was the shooting range, where I meticulously worked up a load for my .338 Winchester Magnum rifle. I tested the Barnes Bullets 30412 TSX 338 Caliber .338 225 GR TSX Flat Base 50 Box in varied weather conditions – from a dry, calm morning to a windy afternoon. I needed to have repeatable results in less than ideal conditions. The range sessions confirmed excellent accuracy, with consistent sub-MOA groups at 100 yards.
Performance remained stellar even in windy conditions. The bullets exhibited minimal drift compared to my previous lead-core loads. They showed a consistently flat trajectory. The bullets punched clean holes through the targets, suggesting a stable flight path.
The bullets were relatively easy to load, though I did find that they preferred a slightly deeper seating depth than recommended in my reloading manuals. I worked up a load that consistently produced excellent accuracy, confirming the bullet’s potential. It didn’t take an excessive amount of time or material.
There were no immediate issues or surprises, other than the bullets’ tendency to copper-foul the barrel slightly more than lead-core projectiles. I needed to clean the barrel more frequently to maintain optimal accuracy. This was easily manageable with a good copper solvent.
Extended Use & Reliability
After several weeks of range testing, I finally had the opportunity to use the Barnes Bullets 30412 TSX 338 Caliber .338 225 GR TSX Flat Base 50 Box during an actual hunt. I took them to Montana for an elk hunt. Over the past month, I’ve put approximately 200 rounds downrange with these bullets.
The bullets have held up remarkably well. The all-copper construction shows no signs of degradation or deformation, even after repeated firing. Accuracy has remained consistently excellent, with no noticeable decrease in performance. I trust that the first shot will be the only one I need.
Maintenance involves regular cleaning of the rifle barrel to remove copper fouling. The Barnes bullets are no harder to clean than other copper bullets, and it is a necessary trade-off for their superior terminal performance. A good copper solvent and a bore brush make quick work of any fouling.
Compared to my previous experiences with lead-core bullets, the Barnes TSX offers a significant upgrade in both accuracy and terminal performance. The consistent expansion and deep penetration have resulted in quicker, more humane kills. It also means more meat preserved after the shot.
