The Redding #23 Standard Bullet Seating Micrometer is the upgrade that takes the guesswork out of dialing in seating depth. Instead of nudging a lock ring and hoping you landed where you wanted, you get a clearly marked micrometer head that lets you adjust and record seating depth in one-thousandth-inch increments. It drops right into your existing seating die as a direct swap for the original seat plug, so there's no new die to buy and no learning curve once it's in.
The #23 uses a standard (STD) bullet profile, which is the right fit for traditional tangent-ogive and spitzer bullets rather than the long, skinny VLD shapes. It's built for the .22 caliber crowd, covering cartridges like the 220 Swift, 22-250 Remington, 223 Remington, 225 Winchester, 222 Remington Magnum, 22 BR Remington, 219 Zipper, 219 Donaldson Wasp, plus the 40-degree Ackley Improved versions of the 22-250 and 223. If you load for a varmint rig or a target .22, odds are good this is the plug for you.
The magic here is repeatability. Once you find the seating depth a particular bullet likes, you note the number on the micrometer and you can return to it exactly, even after swapping bullet weights or pulling the plug for another die. That kind of consistency is what separates "good enough" ammo from the stuff that prints tight groups all day.
This micrometer is designed for seating dies that use a seat plug with 1/2-20 threads, which covers most standard Redding seating dies. Keep in mind it is not made to work with Redding Competition Seating Dies, since those already have a micrometer top built in. Match the number stamped on your current seat plug to the #23 and you're set to swap it over to any die that takes it.
The #23 standard plug is built for the .22 caliber family, including the 220 Swift, 22-250 Remington, 223 Remington, 225 Winchester, 222 Remington Magnum, 22 BR Remington, 219 Zipper, and 219 Donaldson Wasp. It also covers the 40-degree Ackley Improved versions of the 22-250 and 223. The easiest way to confirm fitment is to match the number stamped on your current seat plug to the #23.
No. The Competition Seating Dies already come with a micrometer adjustment built into the top, so this plug isn't meant for them. This #23 micrometer is made to upgrade standard seating dies that use a 1/2-20 threaded seat plug.
The STD plug is shaped for traditional bullet profiles like spitzer and tangent-ogive designs, while the VLD plug is contoured for the longer, more pointed very-low-drag bullets. Running the right plug for your bullet shape keeps contact even and helps prevent tip deformation. This is the standard (STD) version.
The micrometer head lets you set and record seating depth in one-thousandth-inch increments. Once you find the depth a bullet shoots best, you can note the number and return to it exactly, even after switching dies or bullet weights. That repeatability is the main reason handloaders chasing tight groups add one of these.
