Forster Products Ster 7 Prc Dasher Bushing Full Length Sizer Die Kit W/ Bushings 308 310 312

The Forster Bushing Full Length Sizer Die Kit brings bench-tested precision to your 7 PRC and Dasher reloading. If you're building ammo for long-range hunting or target shooting and want repeatable neck tension without over-working your brass, this die system lets you dial in exactly how much grip your case neck applies to each bullet. Unlike standard full-length dies that resize the entire neck uniformly, the bushing approach gives you three different bushing options—308, 310, and 312—so you can find the sweet spot for your specific brass and bullets.

Precision reloaders know that case life and accuracy live or die on neck tension. Too little, and bullets rattle; too much, and you're fatiguing brass prematurely. The Forster bushing system sizes the body and bumps the shoulder to SAAMI minimum chamber specs while the interchangeable bushings control how much the neck is resized. Swap bushings to match your brass lot, your bullet diameter, and your chamber—a level of tuning that standard dies simply don't offer.

This is the kind of tool that pays for itself when you're forming expensive 7 PRC or Dasher brass and expect to reload it five, six, or more times. You get longer case life, tighter velocity spreads, and the kind of consistency that matters when you're dialing in a long-range rig or chasing small groups on the bench.

Frequently Asked Questions

What's the difference between a bushing die and a standard full-length sizer die?

A standard die resizes the entire neck in one fixed dimension. A bushing die lets you swap interchangeable bushings to adjust neck sizing tension independently of body and shoulder sizing. This means you can fine-tune how much the case neck grips your bullet without changing the overall sizing pressure of the die.

Which bushing should I use for my 7 PRC or Dasher brass?

The kit includes three bushings—308, 310, and 312—to cover different brass and bullet combinations. Start with the size closest to your fired case neck diameter and work down if needed. The correct bushing will grip your bullet firmly without over-sizing.

Will this die work with my existing reloading press?

We don't have information on press compatibility in our specs. Contact Forster directly or check the die packaging to confirm fit with your specific press and setup.

What's included in the kit?
