The Lee Precision 243 WSSM Rifle Precision Micrometer Bullet Seating Die brings accuracy and repeatability to your reloading bench without the premium price tag. Built for reloaders who demand consistency shot after shot, this die uses a micrometer adjustment system to dial in exact bullet seating depth—critical for cartridge function, accuracy, and case longevity. Whether you're loading match rounds or hunting ammunition, precise seating depth control is non-negotiable, and this die delivers it in an intuitive, easy-to-read format.
The micrometer thimble is laser-engraved with increments representing one-thousandth of an inch, so you can dial adjustments with confidence and repeatability. Once you establish your preferred seating depth, you'll nail it every time. The floating bullet guide keeps your case and bullet perfectly aligned throughout the seating process, minimizing runout and the risk of bullet damage or marking on premium projectiles. This alignment feature is especially valuable when working with delicate match-grade or bonded hunting bullets.
A distinctive advantage of this die is its reversible floating guide—you can unthread it and reinstall the die to enable simultaneous seating and crimping in a single stroke, a convenience feature often reserved for much pricier equipment. The bullet seating stem itself is machined and burnished to handle virtually any bullet point style cleanly, from hollow points to boat tails. When used as a dead-length seating die, the die body contacts the shell holder, ensuring uniform seating depth from round to round. That precision is what separates consistent, reliable ammo from mediocre handloads.
