Hornady Lock-N-Load Modified Case .300 Savage

The Hornady Lock-N-Load Modified Case in .300 Savage is a precision-machined gauge component made specifically for use with the Hornady Lock-N-Load Precision gauge system, giving the reloader a true-to-chamber reference for measuring bullet seating depth. Its case head carries fine threads for secure attachment to the gauge, and the neck is machined perfectly round and opened .002" oversize so a bullet passes through freely without scraping.

Because the case seats squarely in the chamber, it holds the bullet concentric to the bore for measurements that repeat from round to round. The result is a solid baseline for dialing in seating depth on .300 Savage rifles, letting you tune loads with a known distance to the rifling instead of guesswork.
