Deadly Reloading Mistakes — GMP # 162

This episode of the Guns Magazine Podcast, featuring Tom McHale, delves into critical safety mistakes in reloading ammunition. Key takeaways include understanding extreme pressures, preventing over/undercharging through focus and visual inspection, safe powder handling, the importance of safety glasses, and implementing 'layers' of checks. The discussion emphasizes that if reloading feels like a chore, it's safer to stop or buy factory ammo.

Quick Summary

Reloading safety is paramount. Avoid overcharging by maintaining focus and visually inspecting each powder-filled case with a flashlight. Prevent dangerous squib loads by ensuring proper powder charges. Always wear safety glasses, especially during priming, and implement multiple 'layers' of checks throughout the process to catch errors.

Frequently Asked Questions

What are the most dangerous reloading mistakes to avoid?

The most dangerous reloading mistakes include overcharging cases, which can lead to catastrophic firearm failure due to extreme pressures. Undercharging or creating squib loads is also perilous, as a subsequent round fired into an obstructed barrel can cause an explosion. Improper powder handling and neglecting safety gear like glasses are also critical errors.

How can I prevent overcharging my ammunition when reloading?

To prevent overcharging, maintain unwavering focus during the reloading process, especially with progressive presses. Visually inspect each powder-filled case with a flashlight before seating the bullet. Using powders that fill at least half the case volume also makes double charges more apparent and easier to catch.

Why is it important to wear safety glasses while reloading?

Wearing safety glasses while reloading is crucial because primers are small, explosive devices. During priming operations, there's a risk of accidental detonation, which can send fragments flying. Safety glasses provide essential protection for your eyes against these potential hazards.

What is a 'squib load' and why is it dangerous?

A squib load occurs when a cartridge has insufficient powder or fails to ignite properly, causing the bullet to lodge in the barrel. This is dangerous because if a subsequent, properly charged round is fired into the obstructed barrel, the resulting pressure buildup can cause the firearm to explode.
