This Micro-Adjustable Bullet Seater Cap lets you convert any standard chamber-type L.E. Wilson seater die into a precision-adjustable micrometer seater. Simply replace the cap of your standard seater with Wilson’s micro-adjustable cap, tighten the setscrew on the new cap, and you are ready to fine-tune your bullet seating depth with remarkable accuracy AND repeatability. The L.E. Wilson Micro-Adjustable seater cap accepts Wilson seating stems (drifts) for.17 to .35 caliber bullets. It allows depth to be adjusted in .001" increments, with a .025" depth change per full rotation. Precision-cut 40 tpi threads aid in holding these precise tolerances and provide uncommonly smooth adjustment.

• Precision machined from high-grade 303/316 stainless steel
• No additional bulk: about the same height as standard L.E. Wilson seater cap
• Accepts .17 to .35 caliber Wilson seating stems (drifts)
• Laser-etched markings will never wear off

Like all L.E. Wilson seater die caps, the Micro-Adjustable Bullet Seater firmly holds bullet and case in perfect alignment as the bullet is seated to help increase concentricity and minimize bullet runout.
