Description
Getting neck tension right is one of those details that separates good handloads from great ones, and that is exactly what this Forster .265" neck bushing is built for. It drops into Forster's Bushing Bump Neck Sizing Dies and Bushing Full Length Sizing Dies, letting you size the case neck to your exact spec instead of settling for whatever a standard die hands you. Each bushing is heat treated and honed to the precise inside diameter stamped on it, so the number you see is the number you get.
Why the .265" Forster Bushing Earns Its Spot
The real magic here is control. By swapping bushings in thousandth increments, you fine tune how much grip the neck puts on the bullet, which pays off in tighter groups and brass that lasts longer because you are not overworking the necks every cycle. A common starting point is choosing a bushing about .002" smaller than a loaded round measures at the case neck, then adjusting from there based on your brass and how it behaves after a few firings.
The Cryo Treatment Behind the Smooth-as-Silk Sizing
Forster runs these bushings through a super-cooling cryogenic process after heat treating. That deep freeze refines and closes up the steel's surface, which is why these things feel slick when a neck passes through them. A smoother bushing means less drag, more uniform sizing, and loaded rounds with better concentricity. This .265" size carries the BUSH-265 part number and fits right into the Forster system.
One thing worth knowing up front: Forster bushings are designed for Forster dies and are not cross compatible with Redding or L.E. Wilson bushing dies, so make sure you are running them in the right setup. For anyone chasing repeatable accuracy at the bench, having the right diameter bushing on hand is the difference between guessing and knowing.

Frequently Asked Questions
What dies does the Forster .265" neck bushing work with?
This bushing is made for Forster's Bushing Bump Neck Sizing Dies and Bushing Full Length Sizing Dies. It is not compatible with Redding or L.E. Wilson bushing dies, so you'll want to be running it in a Forster die for a proper fit.
How do I pick the right bushing size for my loads?
A good rule of thumb is to measure the neck of a loaded round and choose a bushing about .002" smaller for proper neck tension. You can also calculate it from your brass neck wall thickness and bullet diameter. Keep in mind brass work-hardens after several firings and may call for a slightly smaller bushing to keep the same grip.
What makes Forster neck bushings different?
Forster heat treats and hones each bushing to the exact inside diameter marked on it, then runs it through a cryogenic process that closes up the steel's surface. The result is a smooth, slick finish that reduces drag and helps produce rounds with better concentricity. It's a small part that makes a real difference at the bench.
Do I need more than one bushing diameter?
Many reloaders keep a few diameters on hand since neck tension can be tuned in thousandth increments. As brass changes over its life and different bullets or cases come into play, having neighboring sizes lets you fine tune grip without guessing. This .265" is one size in that range.
