Lyman Pro Micrometer Seating Die - 308

The Lyman Pro Micrometer Seating Die for .308 delivers repeatable, precision bullet seating for handloaders who demand consistency across every round. This specialized reloading die features a micrometer-adjustable seating head that allows you to dial in exact seating depth to within thousandths of an inch, eliminating the guesswork that leads to inconsistent velocities and point-of-impact shifts downrange.

Built from corrosion-resistant stainless steel, the Lyman micrometer seating die incorporates a floating bullet seating punch that centers each bullet on the case mouth, minimizing run-out and ensuring uniform internal ballistics. The floating design prevents the common problem of excessive run-out that occurs with rigid seating punches, resulting in tighter velocity spreads and improved accuracy potential. Simply rotate the micrometer head to your target depth, and the die delivers that measurement shot after shot—critical for precision rifle loads where even small variations in seating depth can affect performance.

This die is engineered for serious .308 Winchester and .308 match loaders—competition shooters, precision rifle hunters, and bench-rest enthusiasts who understand that consistent ammunition is the foundation of repeatable accuracy. The .308 caliber demands attention to detail, and the Lyman Pro Micrometer Seating Die provides the control necessary to achieve sub-minute-of-angle performance when paired with quality brass, powder, and primers.

Compatible with standard single-stage and progressive reloading presses, this seating die represents an upgrade over standard fixed-depth dies, offering the precision measurement and adjustment capability that separates consistent handloads from mediocre ones.
