Unlock the full potential of your heavy-hitting calibres with ADI AR2218, the ultimate slow-burn rifle powder for big magnums. This is the slowest burning rifle powder in the ADI World Class range, specifically engineered for very large capacity cartridges where case volume is massive and bore diameter is large.

If you are loading for extreme long-range (ELR) shooting or large-bore heavy magnums, AR2218 delivers the consistent, slow pressure curve needed to push heavy projectiles to maximum velocity without dangerous pressure spikes.

Key Performance Features:

1. Extreme Temperature Stability: Like the rest of the ADI "AR" series, AR2218 features ADI's advanced temperature-insensitive technology. This means your muzzle velocities will remain consistent whether you are shooting in the freezing Southern Alps winter or the heat of an Australian summer, critical for ELR accuracy.

2. Clean Burning: Despite being a slow burner, ADI's modern formulation ensures minimal fouling, keeping your barrel cleaner for longer strings of fire.

3. The .50 BMG Standard: AR2218 was originally developed for the .50 Browning Machine Gun (BMG) cartridge but has found a home in other large-capacity wildcats and magnums.

Ideal Calibres:

This powder is generally too slow for standard magnums (like .300 Win Mag or 7mm Rem Mag). It shines in:

• .50 BMG
• .375 CheyTac / .408 CheyTac
• .338 Lapua Magnum (with heavy projectiles 300gr+)
• .30-378 Weatherby Magnum
