The Redding #20 Bullet Seating Micrometer (Redding part no. 09080) is a micrometer-adjustable top designed for Redding Competition Seating Dies, giving handloaders precise, repeatable control over bullet seating depth. Made by Redding, the micrometer graduations let reloaders dial in seating depth changes in small, measurable increments and return to a previous known setting instantly, which is especially valuable when load development calls for seating depth testing across different bullets or powder charges. Instead of guessing or measuring with calipers after every adjustment, handloaders using this micrometer can make fast, accurate changes at the press. For precision rifle handloaders fine-tuning seating depth to the lands, this micrometer top takes the guesswork out of the process.
