Precision-engineered modified case for Hornady Lock-N-Load gauges. Threaded case head, perfectly round neck, and .002" oversized diameter ensure concentrically aligned bullets and repeatable accuracy.
The Hornady Lock-N-Load Modified Case B Series represents a thoughtful solution to a fundamental reloading challenge: achieving perfect concentricity between bullet and case.
Concentricity is the foundation of precision ammunition. When a bullet sits off-center in the case neck, even by a few thousandths of an inch, accuracy suffers. These modified cases eliminate that variable by ensuring your bullets are perfectly centered every single time you seat them.
The fine-threaded attachment system keeps the case perpendicular to your gauge, preventing the tilting and misalignment that can occur with standard cases. This is particularly valuable when working with tight-tolerance cartridges like the 6.5mm-284, where precision separates good groups from exceptional ones.
