What is the muzzle velocity of Lapua 308 Winchester 170 grain Full Metal Jacket?

The listed muzzle velocity is 2756 fps. Muzzle energy is Not Provided in the verified specs, so it should not be assumed from this product page.

Is this Lapua ammo FMJ or FMJBT?

The verified bullet type is Full Metal Jacket, and Lapua describes the projectile as a Lock Base Full Metal Jacket boat tail. FMJBT means the bullet has a full metal jacket profile with a boat tail shape.

What is Lapua 308 Winchester 170 grain Full Metal Jacket intended for?

The verified specs list a brass case and a Boxer centerfire primer. Those are common component details shoppers check when comparing 308 Winchester rifle ammunition.

Is this an expanding hunting load?

The brief identifies the projectile as Full Metal Jacket, not an expanding bullet. Use should be guided by the firearm, the range rules, and the manufacturer-stated tactical and range-oriented role.

How is this Lapua ammo packaged?

The verified packaging is Box of 20 / Case of 600. That gives shoppers a smaller box option and a case option when planning around the same load.

About Lapua 308 Winchester

Lapua 308 Winchester ammunition in this load is built around the 170 grain Lock Base Full Metal Jacket boat tail bullet. In general, an FMJ bullet places a jacket around the projectile for feeding and range use, while a boat tail shape can support aerodynamic efficiency in rifle shooting.

Lapua’s manufacturer copy adds that the patented base design is part of the Lock Base concept. The intended role is tactical, including LE / Mil operations, with suitability for mid-range and long-range shooting.

This is not described as expanding hunting or self-defense ammunition; it is an FMJBT rifle cartridge for shooters who want Lapua’s high-velocity 308 Winchester configuration and verified component details.
