Description

The Redding #13 Flat Bullet Seating Micrometer (part number 09473) turns a standard Redding seating die into a precision, micrometer-adjustable setup. It swaps in for the original #13 seat plug (01073) found in 32 S&W Long and 32 H&R Magnum dies, and the FLAT designation means the stem is shaped to cradle flat nose bullets the way they need to be seated for straight wall revolver cartridges. If you've been chasing consistent overall length on your wadcutter or flat nose loads, this is the upgrade that gets you there without buying a whole new die.

What the #13 Flat Micrometer Does on the Bench

The micrometer is calibrated in .001 inch increments, so adjusting seating depth is a matter of turning the dial instead of guessing with a locknut and a caliper. It's infinitely adjustable through its range, and once you land on a seating depth your gun likes, you can note the setting and return to it later. That repeatability is the whole point. Pull the micrometer to swap bullets or calibers, come back, and you're right back where you left off.

Fit and Compatibility for the Redding #13 Flat Seat Stem

This micrometer uses the common 1/2 inch by 20 thread, which is what Redding's standard seating dies are built around. It's a direct, drop-in replacement for the original seat plug and moves easily from one compatible die to another. Keep in mind it's made for standard Redding seating dies and is not meant for the Redding Competition Seating Dies, which already run their own micrometer system. It also won't fit other brands of dies.

Why Handloaders Reach for a Micrometer Stem

Flat nose and wadcutter bullets in cartridges like 32 S&W Long reward precise, repeatable seating depth, especially if you shoot bullseye or want tidy groups out of a revolver. Rather than fiddling by feel, the dial lets you make small, deliberate changes and track exactly what you did. It's a simple part that makes load development quicker and a lot less frustrating.

Frequently Asked Questions

What cartridges does the #13 Flat seat stem fit?

The 09473 micrometer uses the #13 (01073) flat nose seat stem, which is set up for 32 S&W Long and 32 H&R Magnum. Both cartridges share the .312 bullet diameter and rim dimensions, so the flat stem works for flat nose and wadcutter style bullets in these straight wall revolver loads. If your current seating die shows a #13 stamped on the seat stem, this is your match.

Will the Redding #13 Flat Micrometer work with my Competition Seating Die?

No. This micrometer is built for standard Redding seating dies with the 1/2 inch by 20 thread and is not intended for the Redding Competition Seating Dies, which use their own micrometer setup. It also won't fit seating dies from other brands.

How precise is the seating adjustment?

The micrometer is calibrated in .001 inch increments and is infinitely adjustable through its range. That lets you make small, repeatable changes to seating depth and return to a favorite setting after swapping between dies, which is a big help during load development.

Is the #13 Flat micrometer a drop-in part?

Yes. It's a direct replacement for the original seat plug in a compatible standard Redding die, so you simply remove the factory plug and thread in the micrometer. Because it shares the standard 1/2 inch by 20 thread, you can move it from one compatible die to another as needed.
