Quick Tip: The Truth About Shell Holders

Published on September 2, 2020
Duration: 2:08

This guide addresses a common reloading problem where bottleneck cartridges fail to size correctly for chambering, even with a properly adjusted sizing die. Lead Firearms Instructor Steve from Brownells explains that dimensional variations between shell holder brands are often the culprit. He strongly recommends matching the shell holder brand to the sizing die brand for consistent results. For advanced users needing precise control, he suggests incremental shell holder sets like those from Redding to fine-tune sizing for different brass lots.

Quick Summary

To prevent reloaded cartridges from failing to chamber, ensure your shell holder brand matches your sizing die brand. Dimensional variations between manufacturers can cause inadequate sizing, especially for bottleneck cartridges. For precise control, consider incremental shell holder sets from brands like Redding to fine-tune sizing for different brass lots.

Frequently Asked Questions

Why do my reloaded rifle cartridges not chamber properly?

This common reloading issue, especially with bottleneck cartridges, often stems from dimensional variations between shell holder brands. Even if your sizing die is adjusted correctly, an incompatible shell holder can prevent adequate sizing, leading to chambering problems. Matching your shell holder brand to your sizing die brand is a critical first step to resolve this.

What is the best way to ensure consistent cartridge sizing in reloading?

The most effective method is to ensure your shell holder is the same brand as your sizing dies. This minimizes dimensional inconsistencies that can affect how well your reloaded cartridges fit your firearm's chamber. For advanced reloaders, incremental shell holder sets offer further precision for different brass lots.

Are there specific tools for fine-tuning cartridge sizing?

Yes, for reloaders needing precise control, incremental shell holder sets are available. Brands like Redding offer sets with slight variations in thousandths of an inch. This allows you to fine-tune the sizing process for different batches of brass without altering your die settings, which is particularly useful for match or varmint shooting.

What is the importance of matching shell holder and sizing die brands?

Matching shell holder and sizing die brands is crucial because different manufacturers have slight variations in their manufacturing tolerances. For cartridges that headspace off the shoulder, using mismatched brands can lead to the case not being sized correctly, resulting in chambering issues. This simple step ensures consistent performance and reliability in your reloaded ammunition.
