Redding Now Offers Micrometer Heads for Standard Seating Dies

Redding has introduced a new series of Bullet Seating Micrometers (aka Micrometer Bullet Seater Plug Replacements). These can be retro-fitted into standard Redding seater dies with 1/2-20 thousandths threads, replacing the standard dies’ seater plugs. So, for about forty bucks, you can now make your standard Redding seater die into a Micrometer Seater — and you can swap one Micrometer Seater top among a variety of dies in the same caliber class (such as .223 to 22-250). Notably, the new Bullet Seating Micrometers are offered in two different configurations — one for traditional bullet shapes, and another for VLD bullets. Redding’s new Bullet Seating Micrometers are priced at $48.90 MSRP, but expect to see an initial “street price” of about $37.00-$39.00.

VLD Version of Micrometer Fits Berger Bullets
Eric Stecker of Berger Bullets stated: “I spoke with Redding and confirmed that the new VLD-Version Micrometer plugs are specifically designed for Berger VLD bullets. We provided all of our VLD bullets to them from which they took deliberate measurements and made these new plugs. This is news that needs to be shared with anyone shooting Berger VLD bullets.”

Bad News: You Need Different Micrometer Units for VLD and Non-VLD Bullets
Unfortunately, the Micrometer Seater Plug Replacement is ALL ONE UNIT. You cannot interchange VLD and non-VLD seater stems inside a given Bullet Seating Micrometer. You have to buy one of each (one Micrometer unit for VLD bullets and another Micrometer unit for standard bullets). Likewise, you cannot swap in larger or smaller diameter seater stems to make one Bullet Seating Micrometer head work with dies for widely different bullet diameters. That means you can’t buy one Micrometer head and use it in both a .223 Rem Seater Die and a 30-06 die, for example. You have to stay within the same die class, as explained next.

Good News: Bullet Seating Micrometer — Use in Multiple Dies
As long as you stick with the same seater die class, one Bullet Seating Micrometer can be used on multiple dies. In practical terms, you can usually (but not always) use the same Micrometer assembly on multiple dies within the same caliber family. And when you move the Micrometer unit from one die to another, all you need to record is the Micrometer setting. Look at the photo — the knurled ring at the bottom of the black replacement plug is a dead-stop collar that does not move. That means the lower section of the Micrometer always maintains the same position relative to the die when installed. When moving the Micrometer plug from one die to another, simply adjust the Micrometer knob to the proper setting for that cartridge/bullet. Each hash mark represents an .001″ change in seating depth.

There are sixteen (16) part numbers for the new Bullet Seating Micrometers. These correspond to the VLD and Standard versions for eight (8) different classes of Redding seater dies. To see which Micrometer replacement you need, look for the number on the top of your standard Redding seater, and find that in the right-most column. Then chose whether you want the standard or VLD version (shown in columns one and two on the same line).

Editor’s Comment: We like that fact that Redding is offering these retro-fit Micrometer Seater Plug Replacements. And it’s great that the buyer has a choice between VLD and non-VLD styles. However, we think the lack of interchangeability of bullet seater stems is going to be a “deal-breaker” for many shoppers. Redding obviously wants to sell as many Micrometer Seater Plugs as possible. It doesn’t want you to be able to buy one $40 Replacement plug and use that one product for a half-dozen or more calibers. That’s to be expected. However, we think that, for a given cartridge/caliber, Redding should have engineered the Micrometer Bullet Seater Plug Replacement with swappable seating stems so that one $40 Micrometer head could seat BOTH VLD and non-VLD bullets… at least for that cartridge/caliber.
