The Redding 6mm B.R. Remington Full Length Sizing Die (Part #91317) is precision-engineered to restore fired cartridge brass back to minimum SAAMI factory dimensions while simultaneously decapping the spent primer. Machined from heat-treated alloy steel with hand-polished internal surfaces, this die sizes the entire case body, bumps the shoulder back, and resizes the case neck using an integrated size/expander button. Designed for standard mechanical bench presses, it ensures reliable chambering and consistent headspacing for precision rifle platforms chambered in 6mm BR Remington (.243-inch bullet diameter).

Key Features

• Full-Length Resizing: Resets the case body dimensions, bumps the shoulder, and sizes the neck to maintain dependable feeding and chambering across various rifle actions.
• Simultaneous Decapping: Integrated decapping rod assembly (#32242) and decapping pin (#01059) remove spent primers in the same stroke as sizing.
• Standard Expander Button: Includes internal expander button (#39242) on the stem to establish correct inside neck diameter and tension as brass withdraws from the die.
• Hardened Alloy Steel Construction: Heat-treated alloy steel body with hand-polished interior tooling prevents case galling when used with proper case lubrication.
• Standard Thread Mounting: Outfitted with a standard 7/8"-14 locking ring (#01016) for secure, repeatable installation in compatible reloading presses.

Who is the Redding 6mm BR Remington Full Length Sizing Die for?

• Precision benchrest shooters — who require a full-length sizing die to reliably restore fired 6mm BR Remington (.243 in bullet diameter) cases to SAAMI factory headspace and external dimensions for consistent bolt-closure across match actions.
• Varmint hunters — who need a 7/8"-14 thread sizing die to streamline bottleneck rifle brass prep by resizing the case body and decapping spent primers in a single mechanical press pass.

Less suitable for: Shooters requiring micrometre-level neck tension adjustment without working brass through an expander button (who require a bushing-style full-length sizing die), shooters preserving fire-formed case necks who only require body sizing (who require a dedicated body-only die), or rifles with custom match-tight chambers requiring extreme base reduction (which require a dedicated small-base sizing die).
