Description

Lee Case Length Gauge 50 BMG #90010

The Lee Case Length Gauge .50 BMG #90010 is a caliber-specific trimming tool designed to ensure .50 BMG brass cases are cut to the correct length. It works together with the Lee Cutter and Lock Stud (sold separately) to provide a simple, precise, and repeatable trimming system.

It also includes a matching shell holder, allowing secure case positioning during trimming.

👉 Its main purpose is to:

  • Maintain safe case length
  • Improve consistency and accuracy
  • Prevent issues caused by overgrown brass

The system is factory-set to trim cases within SAAMI length specifications, eliminating guesswork.

 

Best Suited For

  • Reloaders working with .50 BMG rifle cartridges
  • Shooters requiring consistent case length for precision shooting
  • High-volume reloaders needing a fast and repeatable trimming method
  • Beginners looking for a simple, no-measurement trimming solution

Particularly useful for:

  • Long-range shooting setups
  • Precision rifle ammunition
  • Military surplus brass processing

When To Use It

Use this tool during the case preparation stage of reloading:

Typical Use Timing

  • After firing and resizing brass
  • When cases have stretched beyond maximum length

Why It’s Needed

Repeated firing causes brass to elongate, which can:

  • Increase pressure
  • Cause chambering issues

This tool trims cases back to a safe, consistent length automatically.

FAQs

1. Do I need a caliper to set trim length?

No. The gauge is factory-set, so it automatically trims to the correct length.


2. Can I use this without a cutter?

No. It must be used with:

  • Lee Cutter
  • Lock Stud (large version for .50 BMG)

3. Is it adjustable?

No. It is a fixed-length system, which ensures consistency but limits customization.


4. Can I use it for other calibers?

No. Each gauge is caliber-specific, so you need a different gauge for each cartridge.


5. Does it improve accuracy?

Yes—consistent case length helps:

  • Uniform crimp

  • Better overall shot consistency
