Forster Full Length Sizing Die 8.6 Blackout
The Forster Full Length Sizing Die for 8.6 Blackout is a precision reloading die built for shooters who demand concentric, match-grade ammunition. Whether you're working up loads for a new rifle or maintaining a proven load, this full length sizing die gives you the control and consistency that separates handloads from factory ammo. Forster has been the choice of competitive reloaders and precision shooters for decades, and this die carries that same reputation for quality.
Like all Forster dies, the 8.6 Blackout full length sizer starts with premium steel, machined to exacting tolerances and hand polished before and after heat treatment to ensure smooth operation and longevity. The die's engineering focuses on what matters most: keeping your cases and case necks perfectly centered during the sizing stroke. This concentricity directly translates to tighter shot groups and more predictable ballistics downrange.
The standout feature is Forster's E-Z Out Expander button, positioned higher in the neck than conventional designs. This placement provides critical support to the case neck during expansion, maintaining alignment with the case body throughout the operation. When you withdraw the case from the die, the neck stays true—no wobble, no runout. Pair that with Forster's Cross Bolt Die Locking Ring (which tightens both ends of the split ring rather than threading a screw directly into die threads), and you get a die that locks down securely and stays put through hundreds of reloading sessions.
If you're building precision loads for the 8.6 Blackout and refuse to compromise on case prep, this is the full length sizer to reach for.

Frequently Asked Questions
What is a full length sizing die used for?
A full length sizing die resizes the entire case—body, shoulder, and neck—back to factory dimensions. This is essential for ammunition that will be fired in multiple rifles or for maintaining consistent case dimensions across a large batch of reloads. Full length sizing ensures reliable feeding and chambering.
How does Forster's E-Z Out Expander button improve case neck concentricity?
Forster positions the E-Z Out Expander button higher in the neck area than most competing designs. This elevated placement provides physical support to the case neck during the expanding stroke, keeping the neck axis aligned with the case body. When you withdraw the sized case, the neck stays centered, reducing runout and improving accuracy.
Does the Forster Cross Bolt Die Locking Ring require a wrench or special tool?
No. The Cross Bolt Die Locking Ring tightens by hand, clamping both ends of the split ring simultaneously. This design is more secure than screw-locking rings and does not require additional tools.
What reloading press is this die compatible with?
Forster full length sizing dies are designed for standard reloading presses that accept 7/8-14 thread reloading dies. Verify your press compatibility before purchase.
