The purpose of this specific .338 Lapua Magnum ammo is to deliver high-velocity, extreme long-range accuracy with a flat trajectory and minimized drag.

Primary Purposes & Ballistic Design
* Boat Tail Design: The tapered base of the SIERRA boat tail projectile significantly reduces aerodynamic drag in flight, keeping the bullet stable and accurate as it transitions to subsonic speeds at long distances.

* Powder Charge (81.2 Grains): An 81.2-grain charge of slow-burning H4831sc rifle powder acts as a moderate-to-standard loading for a 250-grain projectile in the large .338 Lapua case, pushing the bullet to a solidly efficient muzzle velocitiy of 2750 feet per second (depending on barrel length) without exceeding safe chamber pressures.

* Energy Retention: The 250 grain HPBT combined with this 2750 FPS velocity maintains high kinetic energy well past 2,000 yards.

Common Uses
* Long-Range Target Shooting: Frequently used in Hornady Match or Federal Gold Medal configurations for precision bench-rest and extreme long-range (ELR) steel target competitions.

* Tactical and Military Application: Designed to engage targets or provide sniper capabilities at distances far exceeding standard intermediate cartridges like the .308 Winchester.

* Big-Game Hunting: If the 250-grain boat tail hollow point projectile is an expanding hunting bullet, it is used to take down heavy, tough big game such as elk, moose, and large bears at extended distances.

Hogdon H4831SC Powder
Hodgdon H4831SC is an extreme extruded smokeless rifle powder that is an exact ballistic copy of standard H4831, featuring shorter kernels ("Short Cut") for smoother metering and better packing density.

Key Features
* Ballistic Match: Identical performance and charge weights to standard H4831.
* Short Cut Design: Shorter grains flow smoothly through powder measures without cutting kernels, creating more uniform charge weights.
* Temperature Stable: Part of Hodgdon’s Extreme series, offering resistance to hot and cold weather shifts.

Hogdon H4831SC Rifle Powder has posted more wins than all other propellants combined. It is a fine extruded powder that flows accurately and with ease through measures and delivers match-grade accuracy when put to use.

KINETIC INDUSTRIES – Our OEM manufacture performed well in this assessment, taking 2 Silver and 2 Bronze. Providing rifle brass to cartridge makers requires less focus on retail packaging and more on their ability to deliver quality in staggering quantities. Here consistency is king, as the cases must be “ready to load” when they arrive at the customer. Kinetic's highly consistent case length and runout ensures that the seating depth of the loaded ammo is optimal. In both of these areas, Kinetic took silver.

I have 500 rounds of perfectly kept (air conditioned, dehumidified Fort Knox Safe) .338 Lapua Magnum ammo for sale. 410 rounds is boxed and 100 rounds is in a cam-lock ammo container. This is Match grade ammunition made for accuracy, stability and high energy on target.

I am downsizing my collection and ammo a bit because I am not making time to go shooting.
