Description

Forster has a reputation among precision reloaders for turning out some of the straightest ammo you can build without spending a fortune, and this .243 Winchester full length sizing die is a big reason why. It sizes the case neck and body, bumps the shoulder back to set headspace, deprimes, and expands the neck all in a single stroke. Every die is machined by hand with a solid one-piece reamer from high-quality steel, then hand polished before and after heat treating for a smooth, clean finish that shows in the brass it produces.

What Sets the Forster .243 Sizing Die Apart

The secret sauce here is the elevated E-Z Out expander ball. Instead of yanking the neck over the ball on the way out with the case dangling free, Forster positions the expander higher in the neck so the case is still captured in the die when the neck passes over it. Pair that with the butyl rubber Co-Ax washer that lets the decapping assembly float and self-center, and you get the low runout these dies are known for. In head-to-head brass tests, Forster full length dies routinely come out on top for concentricity, which is exactly what you want feeding a .243 built for tight groups.

Fitment and Setup for the .243 Winchester Die

The die uses the standard 7/8-14 thread, so it drops into any conventional press, and it also carries the Forster die body ring that lets it run in a Co-Ax press. Adjustment is easy thanks to the knurled knobs and the Cross Bolt locking ring, which clamps the split ring evenly rather than digging a screw into the die threads. You'll need a shellholder if you're running a traditional press, though that's not required with a Co-Ax setup.

Getting the Most From Your .243 Reloads

Whether you're loading for a lightweight deer rifle or a varmint gun that lives at the range, full length sizing keeps your brass fitting the chamber like a glove after every firing. If you want to fine-tune neck tension down the road, Forster offers a honing service to size the die neck to your exact spec. It's a quiet trick the accuracy crowd leans on, and it makes this die a long-term keeper.

Frequently Asked Questions

Is the Forster .243 sizing die the same as their Bench Rest die?

Yes. Forster makes only one grade of die, and it's all top quality, so this full length sizer is built to the same Bench Rest standard as everything in their lineup. You're getting the hand-machined, hand-polished die whether the box says Bench Rest or not.

Do I need a shellholder or any extras to use this .243 Winchester die?

If you're running a traditional 7/8-14 threaded press, you'll want a shellholder to match your case head, and that's sold separately. If you use a Forster Co-Ax press, no shellholder is needed since the die body ring handles the fitment.

Why do reloaders say Forster dies produce less runout?

It comes down to the elevated E-Z Out expander ball. Because the neck passes over the ball while most of the case is still held inside the die, the brass stays aligned instead of getting pulled off center, and a floating Co-Ax washer corrects any misalignment. In side-by-side brass tests, Forster full length dies consistently come out among the straightest.

Can I adjust neck tension on this die?

The die comes set for standard neck tension, with the expander ball running about 0.001 inch under bullet diameter. If you want a tighter or more precise fit, Forster offers an inexpensive honing service where you send in fired brass and they open the die neck to your exact spec.
