The Next Generation of Lead-Free Hunting Performance
Lapua’s TRX® (TrueRange Expanding®) product family represents a new generation of premium hunting bullets and factory-loaded ammunition, developed for hunters who demand exceptional accuracy, reliable terminal performance and uncompromising quality in the field.
Combining Lapua’s renowned expertise in precision ballistics with advanced lead-free bullet technology, TRX® products deliver outstanding performance from close-range woodland hunts to demanding long-range shooting scenarios. Whether pursuing deer, wild boar, elk, moose or other game species, TRX® is designed to provide confidence when every shot matters.
Built for Accuracy at Every Hunting Distance
High Ballistic Coefficients for Flat Trajectories and Reduced Wind Drift
At the heart of the TRX® design is an advanced solid-copper bullet featuring a precision-engineered polymer tip and an exceptionally aerodynamic profile. The result is one of the highest ballistic coefficient (BC) values in its class, helping hunters benefit from:
Flatter trajectories
Improved retained velocity
Reduced wind drift
Enhanced long-range stability
Increased downrange energy
These advantages allow hunters to place shots more accurately across a wide range of hunting distances and environmental conditions.
Whether shooting across open fields, mountain terrain or long forest clearings, TRX® provides the predictable ballistic performance needed for confident shot placement.
TrueRange Expanding Terminal Performance
Fast Expansion, Deep Penetration and Maximum Energy Transfer
The Lapua TRX® bullet is designed to perform reliably upon impact while maintaining the structural integrity required for deep penetration.
Its solid-copper construction and polymer tip initiate rapid but controlled expansion, forming a uniform mushroom shape that delivers:
Exceptional energy transfer
Deep penetration
Consistent expansion
Nearly 100% weight retention
Minimal fragmentation
This combination helps ensure rapid incapacitation and ethical harvesting while reducing the need for extensive tracking.
Unlike conventional lead-core bullets, TRX® retains virtually all of its original mass throughout penetration, maximizing effectiveness on both medium and large game animals.
Lead-Free Hunting Without Compromise
As hunting regulations increasingly favor lead-free ammunition, hunters are looking for alternatives that deliver premium terminal performance without sacrificing accuracy.
TRX® answers that demand through: Lead-free solid-copper construction, Excellent environmental performance, Consistent expansion over a broad velocity range, Outstanding penetration and Reliable terminal effect.
The innovative design makes TRX® an ideal choice for hunters seeking a future-ready, high-performance hunting bullet capable of excelling under a variety of regulatory and field conditions.
