Description
If you run a Forster Bushing Bump Neck Sizing Die or a Bushing Full Length Sizing Die, this 0.228" bushing is the piece that lets you control neck tension on your own terms. Instead of relying on a one-size-fits-all expander, you pick the exact inside diameter that matches your brass and your bullet, and the bushing does the sizing. The number stamped on it, .228, is the honed inside diameter, so there's no guesswork about what you're getting.
Why the 0.228" Forster Bushing Earns a Spot on the Bench
Forster builds these bushings in .001 inch increments across more than 90 sizes, which means you can fine tune neck tension in tiny steps rather than big jumps. Each one is heat treated, then honed to the precise stated inside diameter. The .228 size commonly comes into play on smaller calibers like .204 Ruger, where the factory die kit pairs it alongside .226 and .224 bushings to cover a range of brass.
How the Cryogenic Treatment Helps This Neck Bushing
After heat treating, Forster runs these bushings through a super-cooled cryogenic process. That refines the steel's surface and leaves the interior slick, which Forster describes as smooth as silk. A smoother bushing means the brass slides through with less drag, and that consistency shows up as straighter, better concentric loaded rounds at the target.
Picking the Right Neck Bushing Size
Forster's rule of thumb is to choose a bushing roughly .002 inch smaller than your loaded round measures at the case neck. For a quick check, measure the outside neck diameter on several loaded cartridges, take the smallest reading, and subtract .002 inch. Want a firmer grip on the bullet? Subtract .003 inch instead. One thing worth knowing up front: these are made specifically for Forster dies and will not swap into Redding or L.E. Wilson tooling, so keep that in mind if you're mixing brands on your bench.

Frequently Asked Questions
Will this 0.228" Forster bushing work in my Redding or L.E. Wilson die?
No. Forster neck bushings are machined specifically for Forster Bushing Bump and Bushing Full Length Sizing Dies and are not interchangeable with Redding or L.E. Wilson tooling. If you're running a non-Forster die, you'll want a bushing made for that brand instead.
What does the 0.228 number on the bushing actually mean?
That's the honed inside diameter of the bushing in inches. The bushing sizes the outside of your case neck to that dimension, which in turn sets your neck tension on the bullet. Forster hones each bushing to the precise stated size, so the stamped number is what you get.
How do I know if 0.228" is the right size for my loads?
Measure the outside neck diameter of several loaded rounds, use the smallest reading, and subtract about .002 inch to find your bushing size. If you want a tighter grip on the bullet, subtract .003 inch instead. The .228 size is a common fit for smaller calibers like .204 Ruger, but always confirm against your own brass and bullet combination.
Why are Forster bushings cryogenically treated?
After heat treating, Forster runs the bushings through a super-cooled cryogenic process that refines and closes the steel's surface. The result is an ultra smooth interior that lets brass pass through with less drag. That smoothness helps produce straighter, more consistent loaded rounds and extends the life of the bushing.
