Description
If you've been chasing tighter groups and better consistency out of your handloads, seating depth is one of the easiest places to find it. The Redding #19 VLD Bullet Seating Micrometer replaces the original seat plug in your standard Redding seating die and gives you a precision micrometer head that lets you fine-tune seating depth to within 1/1000th of an inch. The #19 head is cut specifically for VLD (Very Low Drag) bullet profiles, so the steeper secant and tangent ogives on those long-range projectiles contact the plug where they should instead of getting marred at the tip.
What the #19 VLD Micrometer Fits
This one is designed for cartridges that share the #19 bushing dimensions, which covers 300 Winchester Magnum, 303 British, 308 Norma Magnum, 300 Savage, 300 AAC Blackout, and 300-221 Remington, among others in that family. It threads into standard Redding seating dies that use the 1/2-20 seat plug, and it drops in as a direct replacement for the plug that came in your die. Worth noting: it's built for standard Redding seating dies, not the Competition Seating Dies, since those already come with a micrometer top.
Why Reloaders Reach for the VLD #19 Head
Swapping over is quick. You back out the old plug, thread this one in, and now every adjustment is marked and repeatable instead of guessing with a locknut and trial seating. The micrometer barrel is graduated so you can record a setting, change bullets or dies, and come right back to the exact depth later. Handloaders working up loads for a particular rifle tend to love being able to move seating depth in measured increments while watching how the groups respond.
Machined from steel and finished to Redding's usual standard, the #19 VLD plug swaps cleanly between dies if you run more than one of these cartridges. It's a small upgrade that makes a real difference in how precisely and consistently you can seat long, high-BC bullets.

Frequently Asked Questions
What does the #19 VLD seating micrometer fit?
The #19 head is sized for cartridges in that bushing family, including 300 Winchester Magnum, 303 British, 308 Norma Magnum, 300 Savage, 300 AAC Blackout, and 300-221 Remington. It threads into standard Redding seating dies that use a 1/2-20 seat plug. Match your cartridge to the #19 designation before ordering so you get the correct fit.
Can I use this with Redding Competition Seating Dies?
No. This micrometer is meant to upgrade standard Redding seating dies that have a plain seat plug. Competition Seating Dies already include a built-in micrometer top, so this piece isn't needed for those.
What's the difference between the VLD plug and the standard plug?
The VLD seat plug is shaped for Very Low Drag bullets, which have long, steep ogives common on high-BC target bullets. The standard plug is cut for more conventional bullet shapes and polymer-tipped designs. Choosing the VLD version helps the plug contact the bullet properly instead of bottoming on the tip.
How precise is the seating adjustment?
The micrometer lets you adjust seating depth in increments of one thousandth of an inch. You can note a setting, swap dies or bullets, and dial right back to the same depth later. That repeatability is what makes it so useful when you're working up a load and testing seating depth.
