Lyman Flash Hole Uniformer & Deburrer

Consistent ammunition begins with attention to detail, and flash hole uniformity is a critical step in precision reloading. The Lyman Flash Hole Uniformer removes internal burrs that can compromise ignition reliability and consistency.

Key Features

  • Steel cutter design — Durable cutting tool inserted through the case neck
  • Adjustable stop collar — Accommodates any cartridge case from .22 to .45 caliber
  • Simple operation — One clockwise turn removes burrs quickly and cleanly
  • Improved ignition — Uniform flash holes enhance primer ignition consistency

How It Works

Insert the tool into the flash hole through the case neck and rotate clockwise. The adjustable stop collar prevents over-cutting and ensures consistent results across all your cases. This straightforward approach makes flash hole uniforming accessible to reloaders of all experience levels.

Why Flash Hole Uniformity Matters

Burrs inside the flash hole can create uneven primer ignition, leading to velocity variations and reduced accuracy. By removing these burrs, you establish a more uniform ignition environment, which translates to tighter shot groups and more predictable ballistics downrange.

The Lyman Flash Hole Uniformer is an essential addition to any serious reloader's bench.
