For any serious handloader, the pursuit of precision and safety is paramount. Every component, from the primer to the projectile, plays a critical role in the final performance of a cartridge. Yet, one often overlooked, but absolutely crucial, factor in achieving consistent, safe, and accurate reloads is the case length. This is where specialized tools like the Lee 90137 Case Length Gauge with Shell Holder for 30-40 Krag become indispensable.
This two-piece set is more than just a measuring device; it's a foundational component for ensuring your reloaded ammunition meets the highest standards of safety and accuracy, particularly for a classic cartridge like the .30-40 Krag. Whether you're a seasoned veteran of the reloading bench or just starting your journey into the meticulous world of handloading, understanding and controlling case length is a non-negotiable step.
Why is Case Length Critical for Handloaders?
Imagine a finely tuned engine; every part must be within specific tolerances to function optimally. Ammunition is no different. The length of a cartridge case significantly impacts several aspects of its performance and safety:
- Chambering Issues: Cases that are too long can bind in the rifle's chamber. This not only makes chambering difficult but can also lead to excessive pressure when the round is fired, as the case mouth is crimped or jammed into the forcing cone/leade of the barrel. This is a significant safety hazard.
- Consistent Neck Tension: The case neck holds the bullet. If the case is too long, the neck may extend too far into the chamber's leade, resulting in inconsistent neck tension. This variability directly affects bullet pull and, consequently, muzzle velocity, leading to reduced accuracy and unpredictable ballistic performance.
- Pressure Spikes: As mentioned, an overgrown case crammed into a chamber can create dangerous pressure spikes. This not only puts undue stress on the firearm but also risks catastrophic failure, potentially causing injury to the shooter. For classic cartridges like the .30-40 Krag, which are often fired in older firearms, maintaining correct pressures is even more vital.
- Accuracy Degradation: Inconsistent case length leads to inconsistent bullet release from the case neck. This minute variation can manifest as significant group dispersion downrange, frustrating target shooters and hunters alike who rely on predictable shot placement.
- Case Life: While it might seem counterintuitive, trimming cases extends their life. As brass is fired and resized, it stretches. Trimming removes this stretched material, preventing it from becoming too long and allowing it to be reformed correctly for future reloads.
For those dedicated to maximizing the potential of their .30-40 Krag rifles, whether for historical shooting events, hunting, or simply enjoying the challenge of reloading a classic round, the Lee 90137 Case Length Gauge is a non-negotiable tool. It addresses these critical issues head-on, providing a simple yet incredibly effective solution.

How to Use the Lee 90137 Case Length Gauge and Shell Holder
Achieving perfectly trimmed cases with the Lee 90137 set is a simple process. While specific instructions may vary slightly depending on your exact trimming setup (e.g., Lee Cutter and Lock Stud, or a power trimmer attachment), the fundamental steps remain consistent:
- Prepare Your Cases: Ensure your .30-40 Krag cases have been decapped and sized. This prepares them for trimming and ensures an accurate measurement.
- Insert the Case into the Shell Holder: Place a sized .30-40 Krag case firmly into the universal shell holder provided in the Lee 90137 set. Ensure it is seated all the way.
- Assemble the Trimming Tool (if using Lee Cutter & Lock Stud):
- Thread the .30-40 Krag case length gauge onto the Lee Cutter. The gauge acts as a stop for the cutter.
- Insert the case, still in its shell holder, into the appropriate hole on the Lock Stud.
- Begin Trimming:
- For manual trimming with the Lee Cutter and Lock Stud: Rotate the cutter with your fingers or a drill (at a low RPM for brass). The cutter will trim the case until it bottoms out against the case length gauge, preventing further cutting.
- For power trimming setups: Follow the specific instructions for your power trimmer, ensuring the Lee 90137 gauge is correctly positioned to act as the length stop.
- Remove and Deburr/Chamfer: Once trimmed, remove the case. The trimming process will often leave a slight burr on the inside and outside of the case mouth. Use a chamfering and deburring tool to remove these burrs. This is crucial for smooth bullet seating and consistent bullet release.
- Inspect: Visually inspect the trimmed case to ensure a clean cut and proper length.
By following these simple steps, you can consistently achieve precise case lengths, setting the stage for safer, more accurate, and more reliable .30-40 Krag reloads.
Common Questions Handloaders Ask About Case Trimming & Gauges
Q: Why is case length such a critical factor in reloading?
A: Case length is critical for multiple reasons: it prevents dangerous pressure spikes by ensuring the case doesn't bind in the chamber, promotes consistent neck tension for reliable bullet seating and release (which impacts accuracy), and helps prolong the life of your brass. Cases that are too long can lead to misfires, dangerous overpressure, and poor accuracy.
Q: How often should I trim my .30-40 Krag cases?
A: The frequency of trimming depends on several factors, including the specific brass, the firearm, and the load. As a general rule, cases should be checked for length after every resizing operation. If they exceed the maximum safe length (as indicated by your Lee 90137 gauge), they should be trimmed. Many reloaders trim every 2-3 firings or whenever they notice stretching.
Q: What happens if my cases are too long?
A: If a case is too long, it can be jammed into the rifling of the barrel when chambered, effectively crimping the case mouth onto the bullet. This can lead to significant and dangerous pressure spikes when fired. It can also cause difficult chambering, extraction issues, and severely degrade accuracy.
Q: Is the Lee 90137 suitable for beginners in reloading?
A: Absolutely. The Lee 90137 is incredibly user-friendly and provides a foolproof method for achieving correct case length. Its simplicity makes it an excellent tool for those new to reloading, helping them establish good habits for precision and safety from the start.
Q: Can I use this gauge for other rifle calibers?
A: No. The Lee 90137 Case Length Gauge is specifically designed and machined for the .30-40 Krag cartridge. Each caliber requires its own dedicated case length gauge to ensure the precise trim-to length unique to that cartridge. Lee Precision offers gauges for a wide array of other calibers.
Q: Does trimming improve accuracy?
A: Yes, indirectly. Trimming ensures that all cases are of uniform length. This uniformity leads to more consistent bullet seating depth, neck tension, and ultimately, more consistent internal ballistics from shot to shot. Consistency is the cornerstone of accuracy, so by promoting it, trimming plays a vital role in achieving tighter groups.
