Description
The 22 GT has earned its spot among the top cartridges in precision rifle competition, and getting the most out of it starts with good brass prep. This Forster full length sizing die handles the case neck and body, bumps the shoulder back to set headspace, deprimes, and expands the neck in a single pass. It's built from quality steel and machined to tight tolerances, which is a big part of why Forster dies have the reputation they do for turning out concentric, repeatable ammo.
What Sets This 22 GT Die Apart
The standout feature here is the E-Z Out floating expander ball. Instead of a fixed spindle that can tug the neck off-center on the way out, Forster's floating design self-aligns while most of the case is still held inside the die. That keeps runout low and bullet grip even, which translates directly to tighter groups downrange. The expander ball runs about .001 inch under bullet diameter, so factoring in a bit of brass springback you end up with roughly .002 inch of grip, right in the sweet spot for match loads.
Running the 22 GT Full Length Sizing Die
One of the nicer things about a full length die is flexibility. It'll return brass back to factory specs when you need it, but if you're loading for a single rifle you can back it off slightly to partial size and hold onto your fire-formed dimensions. The die body ring threads into any standard 7/8-14 press, and it drops right into a Forster Co-Ax as well. If you're using a Co-Ax you won't need a shellholder; running it in another press just means grabbing the shellholder your press maker recommends.
Why 22 GT Loaders Reach for Forster
For a cartridge built around accuracy, your dies matter as much as your components. The knurled adjustment knobs make dialing in shoulder bump straightforward, the decapping assembly is adjustable with a hardened pin, and the whole thing is made in the USA. It's a workhorse piece that earns its keep on the loading bench season after season.

Frequently Asked Questions
Does the 22 GT full length sizing die come with a shellholder?
No, a shellholder is sold separately. If you're running the die in a Forster Co-Ax press you won't need one at all, since the Co-Ax uses its own jaw system. For any other 7/8-14 press, grab the shellholder recommended by your press maker.
Will this die work in presses other than a Forster Co-Ax?
Yes. The die body ring threads into any standard 7/8-14 press as well as the Forster Co-Ax. It's a full length die, so it sizes the neck and body, bumps the shoulder, deprimes, and expands the neck in one stroke.
Can I use this 22 GT die to partial size for a single rifle?
You can. The die will bring brass back to factory specs when needed, but you can back it off slightly to partially resize and retain your fire-formed dimensions. That's a common approach when you're loading for one chamber and want to minimize brass working and extend case life.
What makes the E-Z Out expander worth it?
The floating expander ball self-aligns as the neck passes over it while most of the case is still captured in the die. That corrects spindle misalignment and keeps the neck from pulling off-center, which improves concentricity and gives you more consistent bullet grip. For a precision cartridge like the 22 GT, that consistency shows up on target.
