Will the RCBS 7mm x 64 Bren Full Length Die Set fit my standard single-stage reloading press?

Yes, the RCBS 34001 die set features industry-standard 7/8"-14 thread sizing, making it universally compatible with almost all single-stage and turret reloading presses available on the market. You will simply screw the dies directly into your press frame.

Can I use this die set to reload other 7mm rifle cartridges like 7mm Remington Magnum?

No, this die set is strictly engineered for the 7x64mm Brenneke calibre. It cannot be used for 7mm Remington Magnum or 7mm-08 Remington due to critical differences in case body taper, shoulder angles, and overall headspace.

Do I need to lubricate my cartridge cases before using the RCBS full-length sizer die?

Yes, case lubrication is mandatory before running brass into the 34001 sizer die. Because these are hardened steel dies rather than carbide, attempting to resize unlubricated cases will result in a stuck case requiring a separate removal tool.

What shell holder do I need to purchase alongside this RCBS die set for Australian 7x64mm reloading?

You will need an RCBS #1 shell holder, which is sold separately. This shell holder securely grips the rim of the 7x64mm Brenneke brass so it can be reliably pulled into both the sizer and seater dies during your reloading sessions.

How should I maintain these steel dies to protect them from rust in humid Australian workshops?

To prevent rust and corrosion in high-humidity Australian climates, keep the dies clean and apply a very light coat of gun oil or protective solvent to the exterior metal surfaces after use. Store them in their original box in a dry environment.

7x64 Brenneke Die Set - RCBS R34001

The RCBS Full Length Die Set — 7mm x 64 Brenneke (Part Number 34001) is a professional-grade, two-die steel reloading set engineered to resize, de-prime, and seat bottleneck rifle cartridge cases. Machined from hardened, proprietary die steel, this mechanical handloading tool restores fired brass to SAAMI minimum factory dimensions, ensuring smooth chambering and reliable cycling in repeating rifles. Operating entirely via manual leverage, this set requires no electrical power, making it fully compatible with any Australian reloading workshop setup without regulatory electrical certifications.

Key Features

Full-Length Sizer Die: Features an integrated expander-decapping unit that resizes the outer cartridge body, removes spent primers, and expands the case neck to the exact diameter required for standard .284" (7mm) bullets.
Vented Design: Designed with internal air vents to safely release trapped air and prevent hydraulic case denting from excess lubricant during the sizing stroke.
Seater Die: Equipped with an internal bullet seating plug and an integrated roll crimper, allowing handloaders to seat the bullet to depth and apply a secure crimp in a single operation.
Premium Steel Construction: Machined with fine body knurling to provide a slip-free grip for precise, repeatable manual adjustments.

Who is the Rcbs 7mm X 64 Bren Full Length Die Set for?

7x64mm Brenneke rifle hunters and shooters in Australia — who require a reliable reloading tool to restore fired bottleneck cases to original factory specifications, utilizing the standard 7/8"-14 thread sizing to fit universally into their existing single-stage or turret presses.
Handloaders seeking full-length case resizing for repeating rifles — who need to ensure flawless chambering in semi-automatic, pump, or lever-action actions by resizing the entire body of 7x64mm Brenneke brass and utilizing an RCBS #1 shell holder to process their cases.

Less suitable for: Reloading other 7mm variations such as the 7mm Remington Magnum or 7mm-08 Remington, as the proprietary chamber dimensions of this set will not fit their differing shoulder angles and body tapers. It is also unsuitable for dry, unlubricated cases because the steel sizing die requires high-quality case lubricant to prevent stuck cases. For extreme long-range precision shooters wishing to minimize brass working, a neck-sizing-only die or a bushing die is a more suitable option to maximize brass life.
