If you're chasing tighter groups with Very Low Drag bullets, the hardest part is getting seating depth repeatable from round to round. The Redding #20 VLD Bullet Seating Micrometer solves that by replacing the standard seat plug in your Redding seating die with a micrometer-adjustable head designed for the long, streamlined ogive of VLD projectiles. Match the number stamped on your existing seat plug to the #20 micrometer and you've got a precision tool that reads in increments of one thousandth of an inch.
This #20 covers a popular lineup of .30 caliber cartridges, including .308 Winchester, .30-06 Springfield, .300 Winchester Short Magnum, and .300 Remington Ultra Magnum, among others that share the same seat plug number. It threads into any seating die that uses a 1/2-20 seat plug, so it's not locked to a single die. Because the micrometer is a direct drop-in replacement, you can pull it from one die and move it to another without losing your settings, which is handy if you load several cartridges off the same bench.
The seat plug itself is machined from steel alloy and hand finished, with an internal profile cut specifically for VLD nose shapes rather than standard or polymer-tipped bullets. That VLD-specific contact point is the whole point here. It grips the bullet higher up the ogive so you aren't denting a long, thin nose while chasing those last few thousandths toward the lands.
Setup is quick. Mount your seating die as usual, loosen the lock ring, remove the original seat plug, and thread the micrometer in its place. If your die was already set for a proper crimp, you won't need to touch that function. From there you can fine-tune depth, record the setting, and return to it later with real repeatability. For handloaders dialing in jump to the lands on a precision rifle, that kind of consistency is where accuracy lives.
One thing to keep in mind: this micrometer is built for standard Redding seating dies and is not intended for use with Redding Competition Seating Dies, which already have their own micrometer built in.
It's designed for standard Redding seating dies that use a 1/2-20 seat plug. The easiest way to confirm fit is to check the number stamped on your current seat plug and match it to this #20. It's made for Redding dies and won't work with other brands.
The #20 covers a range of .30 caliber cartridges that share the same plug number, including .308 Winchester, .30-06 Springfield, .300 Winchester Short Magnum, and .300 Remington Ultra Magnum. Since Redding groups cartridges by seat plug number, several other calibers fall under #20 as well. Always verify against the number on your existing plug.
No. This micrometer is meant for standard Redding seating dies, not the Competition series. Competition Seating Dies already come with a built-in micrometer, so this replacement plug isn't needed for those.
The VLD seat plug has an internal profile cut specifically for the long, sleek ogive of Very Low Drag bullets. It contacts the bullet higher on the nose, which helps avoid marring that thin tip while you fine-tune seating depth. If you're loading standard or polymer-tipped bullets, the STD micrometer is the better match.
