Barnes Triple-Shock X (TSX) 7mm 150 Grain HPBT Lead-Free Bullets - Box of 50

Barnes Triple-Shock X (TSX) 7mm 150 grain HPBT lead-free bullets are purpose-built for hunters who reload and demand maximum terminal performance on big game. Constructed from 100% copper, these projectiles represent a serious step up from conventional jacketed bullets—offering the stopping power serious long-range hunters expect without the environmental footprint of lead ammunition. Whether you're handloading for elk, mule deer, or similar game, the TSX delivers the kind of controlled expansion and penetration that turns opportunities into clean, ethical kills.

The engineering behind the Triple-Shock X centers on a simple principle: expansion that works reliably across a wide range of velocities and distances. Upon impact, the bullet expands and creates four razor-sharp petals that cut deep into vital areas while the all-copper construction ensures the projectile retains 100% of its original weight, driving through heavy bone and dense tissue without shedding material. That weight retention means deeper penetration and more consistent terminal ballistics downrange—critical factors when your shot has to count.

Reloaders will appreciate the engineering consistency Barnes brings to the table. Seating depth matters, and the manufacturer recommends setting these bullets 0.03 to 0.07 inches off the lands based on your individual rifle's chamber. Start at the conservative end, ladder-test through your load development process, and you'll find the sweet spot where accuracy peaks. This attention to detail in both bullet design and load development is what separates hunters who occasionally connect from those who consistently deliver one-shot performance.

Each box contains 50 bullets—enough to develop a load and build a meaningful hunting supply. If you're serious about handloading for big game with a modern, lead-free option that performs, the Barnes TSX in 7mm 150 grain belongs on your bench.

Frequently Asked Questions

What game is the 7mm 150 grain TSX suitable for?

The Barnes Triple-Shock X is designed for big game hunting. The 7mm 150 grain is a versatile weight commonly loaded for elk, mule deer, and similar medium to large game at extended ranges.

Do I need to adjust my load data when switching from jacketed to Barnes TSX bullets?

Load data can vary between bullet types, weights, and individual rifles. Always consult published reloading manuals specific to the Barnes TSX and your caliber, and start at the conservative end of the charge weight range. Ladder-testing will help you find the sweet spot in your rifle.

Why does seating depth matter so much with the TSX?

The manufacturer states that best accuracy is achieved when seating from 0.03 to 0.07 inches off the lands, depending on your rifle. This narrow window reflects the precision engineering of the bullet and the importance of matching it to your chamber. Start conservative and work up.

Are these bullets truly lead-free?

Yes. The Barnes TSX is constructed from 100% copper, making it a lead-free option for hunters in areas with lead ammunition restrictions or for those who prefer environmentally responsible ammunition.
