Duration: 49:31

This video provides a comprehensive overview of using cast and plated bullets for handloading, emphasizing cost savings and performance. It delves into the science behind bullet alloys, hardness testing, and preventing leading in barrels. The instructor also covers the differences between plated and jacketed bullets and offers practical advice on safe casting practices.

Quick Summary

Handloading with cast bullets can dramatically reduce ammunition costs, potentially by 20 times or more, especially with affordable lead sources. Key to preventing barrel leading is understanding that pressure, not just velocity, is the primary factor, alongside bullet hardness and proper obturation.

Frequently Asked Questions

How can I save money when handloading ammunition?

A significant way to save money when handloading is by using cast or plated bullets instead of jacketed bullets. Cast bullets, especially if you can source lead affordably, can reduce costs by up to 20 times or more, making reloading much more economical.

What causes leading in a firearm barrel when shooting cast bullets?

Leading in a firearm barrel from cast bullets is primarily caused by friction and hot gas blow-by, rather than just high velocity. The hardness of the bullet alloy, proper fit, and sufficient pressure for obturation are key factors in preventing this residue buildup.

How do I measure the hardness of cast bullets?

You can measure cast bullet hardness using tools like the Lee Hardness Testing Kit. This kit uses a spring-loaded device to create an indentation on the bullet, which is then measured with a microscope to determine the Brinell hardness, correlating to safe pressure limits.

What is the difference between plated and jacketed bullets?

Plated bullets have a thin electroplated copper coating over a lead core, while jacketed bullets have a much thicker copper jacket. Plated bullets are less durable and can be damaged by aggressive crimps, making them best suited for lower velocities and recreational shooting.

What are the safety concerns with casting bullets?

Casting bullets involves working with molten lead at high temperatures and toxic fumes, posing risks of lead poisoning and burns. It is crucial to cast bullets outdoors or in a well-ventilated area, wear protective gear, and follow safe handling procedures to mitigate these hazards.
