Description
Redding's Small Base Body Die for the 30-06 Springfield is a specialty tool built for handloaders who need their brass sized down to the bare minimum. It full-length resizes the case body and sets the shoulder back for proper headspace, all without disturbing the neck. The small base part is what sets it apart: it squeezes the brass tighter than a standard body die, bringing cases back toward minimal dimensions so they drop in and feed reliably. That makes it a go-to for custom chambers cut tight and for semi-automatic rifles where dependable feeding matters as much as accuracy.
What the 30-06 Small Base Body Die Does Differently
Regular full-length dies resize the neck as the case comes back out, which many precision reloaders would rather avoid. This body die skips the neck entirely, so you can keep body sizing and neck sizing as two separate operations. Running the neck on a dedicated bushing or collet die tends to produce straighter, more concentric loaded rounds with less runout. There's no decapping rod and no moving internal parts, just clean, repeatable body and shoulder sizing every pull of the handle.
Getting the Most From Your Redding Small Base Body Die
Shoulder bump is where this die earns its keep. You control how far the shoulder moves back by adjusting the die's position relative to the shellholder, and for fine-tuning that bump, Redding Competition Shellholders are the recommended companion. Because a small base die works the brass harder than a standard sizer, don't skimp on good case lube. A proper coat keeps cases from sticking and keeps the job smooth.
This die pairs naturally with a Redding Type S or Competition neck sizing die to round out a two-step workflow. Machined in the USA from quality tool steel and backed by Redding's reputation for precision, it's a reliable piece for anyone loading 30-06 for an AR-10, M1A, Garand, or a tight-chambered bolt gun that's gotten fussy about chambering after a few firings.

Frequently Asked Questions
What is the difference between a small base body die and a standard body die?
Both resize the case body and bump the shoulder without touching the neck. The small base version sizes the brass down tighter, closer to minimum dimensions, which helps cases chamber and feed in tight chambers and semi-automatic rifles. If you're loading for an AR-10, M1A, or Garand in 30-06, the small base sizing adds a margin of reliability.
Does the Redding Small Base Body Die size the case neck?
No. This die works the body and shoulder only and leaves the neck untouched. You'll want to pair it with a separate neck sizing die, such as a Redding Type S bushing or Competition neck die, to size the neck in its own step for straighter, more concentric rounds.
Do I need a special shellholder for this body die?
A standard shellholder works for basic sizing, but Redding Competition Shellholders are recommended if you want precise control over how far the shoulder gets bumped. They let you fine-tune headspace in small increments. These shellholders are sold separately.
Does this die come with a decapping rod?
No, the Small Base Body Die has no decapping rod and no moving internal parts. It focuses purely on body and shoulder sizing. You'll handle primer removal and neck sizing with your other dies in the process.
