Description

Lee Full Length Decapping pin 7.62x39 .311 SE1935

The Lee High Carbon Steel Sizing Die resizes the case to the correct size while also depriming the previous primer. Reloaders never know when a component will fail, so be ready with high-quality replacement parts.

Fits: 7.62x39 Russian
 

Best Suited For

  • Reloaders using 7.62×39 rifles with .310–.311 bore diameters
  • Owners of AK-pattern and SKS rifles
  • Users of Lee Pacesetter or RGB full-length sizing dies
  • Reloaders working with .311 diameter bullets (common for Russian-spec barrels)
  • Replacement of worn or damaged expander/decapping assemblies

When To Use It

Use the SE1935 decapping pin when:

  • You are loading .310–.311 bullets and need correct neck expansion
  • The original decapping pin/expander is damaged, bent, or missing
  • You experience excessive neck tension or difficulty seating bullets
  • Performing die maintenance or converting between expander sizes

It is especially important when switching from .308 to .311 projectiles, as the correct expander ensures proper bullet seating and prevents case damage.

FAQs

Q1: Is this the same as SE2024?
No. SE2024 is typically used for .307/.308 expansion, while SE1935 is designed for larger .310–.311 bullets.

Q2: Does this include the full decapping rod?
Yes—this version is typically supplied as an EZ X Expander/decapping rod assembly, not just the pin.

Q3: Why do I need a .311 expander?
Because many 7.62×39 rifles use larger bore diameters, and using a smaller expander can cause excessive neck tension or bullet deformation.

Q4: Can I use this with .308 bullets?
Not recommended. It may result in insufficient neck tension.

Q5: What causes decapping pins to fail?

  • Berdan-primed brass
  • Obstructed flash holes
  • Excessive resizing force
  • Misalignment in the die
