Description
The Forster 0.271" Neck Bushing is the small part that makes a big difference when you're chasing tighter groups. It drops into Forster's Bushing Bump Neck Sizing Dies and Bushing Full Length Sizing Dies, giving you direct control over exactly how much your case necks get squeezed down. Instead of relying on a one-size expander ball, the bushing itself sets the interior neck diameter, so you can tune neck tension to match your brass and your rifle.
What the 0.271" Bushing Does for Your Loads
Neck tension is one of those details that separates plinking ammo from match-grade handloads. By picking the right diameter bushing, you choose how far the neck gets sized and how firmly it grips the bullet. A common starting point is selecting a bushing roughly .002 inch smaller than a loaded round measures at the neck, and since these come in .001 inch increments, you can fine-tune from there. This particular unit is honed to a 0.271 inch interior diameter.
Why Forster Neck Bushings Hold Up
Forster doesn't cut corners on these. The steel goes through a super-cooling cryogenic process that refines and closes the surface, then each bushing is heat treated and honed to the stated inside diameter. The result is an ultra-smooth interior that sizes necks cleanly and consistently, which shows up as better concentricity and more uniform seating from round to round.
Keep in mind this is a Forster-specific bushing. It's built to run in Forster's bushing dies and isn't cross-compatible with Redding or Wilson bushing systems. If you're already running a Forster Bushing Bump or Bushing Full Length die, the 0.271" bushing is a straightforward way to add another tension option to your bench. Serious handloaders often keep a small spread of sizes on hand so they can adjust as their brass work-hardens over repeated firings.

Frequently Asked Questions
What dies does the 0.271" neck bushing work with?
This bushing is designed for Forster's Bushing Bump Neck Sizing Dies and Bushing Full Length Sizing Dies. It is a Forster-specific bushing and does not interchange with Redding or Wilson bushing systems. If you run Forster bushing dies, it drops right in.
How do I pick the right bushing size for my brass?
A good rule of thumb is to measure the neck diameter of a loaded round, then choose a bushing about .002 inch smaller for proper neck tension. Forster offers these in .001 inch increments so you can fine-tune. The right size depends on your brass neck wall thickness, so measuring your own loaded rounds is the way to go.
Why does the 0.271" bushing matter for accuracy?
The bushing sets the interior neck diameter and controls how much tension grips the bullet, which affects concentricity and consistency shot to shot. Forster's cryogenic treatment and honing give it a very smooth interior, so necks size cleanly without overworking the brass. Controlling neck tension this precisely is a big part of building repeatable, match-quality loads.
Will I need more than one bushing size?
Many handloaders keep a small range of sizes on the bench. As brass is fired and resized over time the necks work-harden and spring back slightly differently, so having a bushing or two on either side of your target gives you room to adjust. It also helps when you load for more than one rifle or brand of brass.
