The Varminter bullet

At the heart of this .260 Rem 100gr Sierra is the Varminter, chosen to match the supersonic role this load is built for. It is loaded on factory-new brass to consistent tolerances, the foundation of both reliability and accuracy.

That round-to-round consistency is what lets the load shoot to the same point of impact shot after shot — exactly what you want whether you are hunting, training or competing.

Supersonic performance and reach

This .260 Rem 100gr Sierra runs supersonic for a flatter trajectory and more retained energy downrange, extending your practical range. You trade the whisper-quiet subsonic signature for velocity and on-target authority.

It is a strong choice when reach, speed and energy matter more than maximum quiet, and it performs from the short barrels the cartridge was built around.

What it is best for

This .260 Rem 100gr Sierra suits hunting, defense and general-purpose shooting at supersonic ranges. Match the load to your task, confirm your zero before you rely on it, and it rewards you with dependable performance.

Different loads print to different points of impact, so always verify your zero with this specific round. For help choosing, read our 300 Blackout vs 5.56 guide.
