In-the-know shooters understand that Lapua, as a company, is all about performance. The initials in the TRX series name stand for True-Range Expanding. The bullets used in these rounds are built to mushroom even at the extended distances that hunters are increasingly shooting over.

We actually had our first look at the TRX series back in 2025. Here’s what Daniel told you then:

“Marketing images from Lapua show expansion as slow as 1640 FPS, and weight retention of 99%.

Lapua has three TRX component bullets in this initial release:

6.5mm 120-grain, .428 G1 BC

.308 150-grain, .384 G1 BC

.308 165-grain, .490 G1 BC

Three loaded ammunition options using the TRX bullet are also coming soon. Those include:

6.5 Creedmoor 120-grain

6.5x55 Swede 120-grain

308 Winchester 165-grain

This ammo is loaded with Vihtavuori powder, and features the patented Air Lock technology that makes the ammunition waterproof for hunting in wet conditions.”
