Description
This is the Forster .272" neck bushing, part number BUSH-272, one piece in Forster's lineup of over 90 bushing sizes offered in .001" increments. It drops into your Forster sizing die and gives you direct control over how much your case necks get worked, which is where a lot of accuracy and brass life comes from. The inside diameter is honed to the exact .272" stated, so you know what you're getting when you set up a load.
What separates these from a lot of bushings on the market is the cryogenic treatment. After heat treating, Forster runs the steel through a super-cooling process that refines and tightens the surface, leaving a slick finish that sizes smoothly and holds up over a long reloading life. That ultra-smooth surface matters more than it sounds like it should, because a bushing that drags leaves marks on the brass and adds inconsistency round to round.
Where the .272" Bushing Fits In Your Reloading Setup
This bushing works with the Forster Bushing Bump Neck Sizing Die and the Bushing Full Length Sizing Die. Worth noting up front: these are made for Forster dies only and will not swap into Redding or L.E. Wilson tooling. A common pairing for the .272" size is the .243 Winchester, where Forster's die kits ship with .272", .270", and .268" bushings to cover the usual neck tension range.
Dialing In Neck Tension with the BUSH-272
Picking the right bushing comes down to a quick measurement. The standard method is to measure the outside neck diameter of a loaded round and subtract about .002", or run the formula of neck wall thickness times two plus bullet diameter, then subtract .002". Want a firmer grip on the bullet? Subtract .003" instead. The beauty of the bushing system is that it sizes the neck without overworking it, so your brass lasts longer and stays better aligned to the case centerline. If your necks vary in wall thickness, turning them first will get the most out of a bushing setup.

Frequently Asked Questions
What dies does the Forster .272" neck bushing work with?
The BUSH-272 is designed for the Forster Bushing Bump Neck Sizing Die and the Forster Bushing Full Length Sizing Die. It is not compatible with Redding or L.E. Wilson dies, so it needs to be paired with Forster tooling. If you already run a Forster bushing die, this bushing drops right in.
How do I know if .272" is the right bushing size for my load?
Measure the outside neck diameter of a loaded round and subtract about .002" for standard neck tension. You can also use the formula of neck wall thickness times two, plus bullet diameter, minus .002". If you want a tighter grip on the bullet, subtract .003" instead. The .272" size commonly suits .243 Winchester loads.
Why is the Forster bushing cryogenically treated?
After heat treating, Forster runs the bushings through a cryogenic super-cooling process that refines and closes the steel's surface. The result is an ultra-smooth bushing that sizes case necks cleanly and holds up over a long reloading life. A slicker bushing also means less drag and more consistent necks round to round.
Does this bushing control neck tension on its own?
Yes. In the Forster bushing bump die the decapping assembly does not use an expander ball, so your bushing selection determines the inside neck diameter and the resulting bullet tension. Because it only works the neck as much as needed, it helps avoid overworking your brass and keeps the neck aligned to the case centerline.
