This guide details the process of annealing brass cases, a crucial step in reloading to prevent neck splits and ensure consistent resizing. It covers both automated machine methods (Annealeez, AMP Mark II, Bench Source) and DIY torch techniques, emphasizing the importance of heating only the neck and shoulder. Expert instruction highlights the benefits for rifle and some pistol calibers, while cautioning against improper techniques.

Quick Summary

Annealing brass cases softens the neck and shoulder, preventing work hardening and neck splits, and reducing case spring-back for consistent resizing. Methods include flame annealing (Annealeez, Bench Source) and induction annealing (AMP Mark II), with rifle calibers benefiting most.

Frequently Asked Questions

What is the primary benefit of annealing brass cases?

Annealing brass cases softens the neck and shoulder, which prevents work hardening. This significantly reduces the likelihood of neck splits during firing and resizing, extending the useful life of your brass.

What are the main types of brass annealing methods discussed?

The video covers flame annealing (using torches or machines like Annealeez and Bench Source) and induction annealing (using machines like the AMP Mark II). DIY methods using a drill and torch are also shown.

Which calibers benefit most from annealing?

Rifle brass generally benefits the most from annealing. While .300 Blackout is specifically mentioned for preventing neck splits, most pistol calibers like 9mm and .45 ACP are typically not annealed by reloaders.

What is the difference in cost between flame and induction annealers?

Flame annealers like the Annealeez ($275) and Bench Source ($600) are more budget-friendly. High-end induction annealers like the AMP Mark II can cost $1500 or more, representing a significant investment.
