Description

When you're loading something as serious as 338 Lapua Magnum, the seating die is where your precision work either pays off or falls apart. The Redding Competition Seater is widely regarded as one of the most accurate and consistent bullet seating dies made, and it earns that reputation by solving the concentricity headaches that plague cheaper seaters. Instead of letting the case wobble during seating, this die fully supports and aligns the case and bullet inside a close fitting, precision ground sleeve before the bullet ever starts moving. That alignment is the difference between loaded rounds that shoot and loaded rounds that just look good.

How the 338 Lapua Competition Seater Keeps Things Straight

The heart of this die is its patented seating stem system. The stem is precision ground to match bullet diameter exactly, and the fit between the stem and the bullet guide is tight enough that you can see the slight vacuum it creates when things move. A spring loaded sleeve captures the case and pushes it up to meet the stem, so nothing shifts during the stroke. The result is seated bullets with consistently low runout, round after round.

Dialing In Seating Depth on the 338 Lapua Magnum Seating Die

Up top you get a micrometer adjustment head calibrated in .001 inch increments. The adjustment is click free and infinitely adjustable, so you can fine tune seating depth to the exact number you want rather than settling for the nearest click. There's also a zero set feature, which lets you mark your favorite depth or set it for a specific rifle and return to that setting whenever you want. If you run multiple bullets or multiple rifles, that repeatability saves a lot of trial and error at the bench.

The die uses standard 7/8 inch by 14 threads, so it drops right into the common reloading presses you already own. Keep in mind this is a seating only die and does not crimp, which is exactly how most precision handloaders want it for the 338 Lapua. Like all Redding tooling, it's machined and finished in the USA.

Frequently Asked Questions

Does the 338 Lapua Magnum Competition Seating Die crimp the bullet?

No, this is a seating only die and does not apply a crimp. Most precision handloaders prefer it this way for the 338 Lapua, since a crimp can hurt consistency on long range loads. If you want to crimp, you'll need a separate crimp die.

Will this Redding die fit my reloading press?

Yes, it uses standard 7/8 inch by 14 threads, which is the common standard across most popular single stage and turret presses. It should thread right into whatever setup you're already running. Just note a shellholder is sold separately.

What makes the Competition Seater different from a standard 338 Lapua seating die?

The big differences are the sliding chamber sleeve and the micrometer head. The sleeve fully captures and aligns the case and bullet before seating begins, which cuts down on runout, while the micrometer lets you dial seating depth in .001 inch increments. A standard seater adjusts by threading the stem in and out, which is far less precise and harder to return to a set depth.

Can I set a repeatable seating depth with this die?

Yes, the micrometer head has a zero set feature that lets you zero in on a favorite seating depth or a setting for a specific rifle. Because the adjustment is click free and infinitely adjustable, you can hit any number you want and come back to it later. That repeatability is a big help if you load several bullets or shoot more than one 338 Lapua.
