Sinclair International has produced an eight-part video series on metallic cartridge reloading, hosted by Sinclair’s former President Bill Gravatt. The entire series can be viewed (for free) via Sinclair’s YouTube Channel. While this set of videos starts with the basics, it covers many more advanced aspects of reloading as well. Accordingly, both novice and experienced reloaders can benefit from watching the eight videos. We think everyone should watch Video No. 2. Introduction to Reloading Safety, which provides guidelines for safe reloading practices.

Watch Firing Sequence Video

We also strongly recommend Video No. 4 to readers who are getting started in reloading. This “How Things Work” segment covers the sequence of events inside the chamber (and barrel) when the cartridge is fired. The video includes helpful graphics that show what happens to the primer, powder, cartridge, and bullet when the round is fired. The video also illustrates “headspace” and explains how this can change after firing. We think this video answers many common questions and will help reloaders understand the forces at work on their brass during the firing process.
