Nosler, like Hornady, is a bullet manufacturer, so a fair amount of space
in the beginning of the manual is devoted to Nosler bullet manufacturing.
Included are some very good cutaway views of various types of Nosler bullets,
with a description of their characteristics.
The Introduction to Reloading section is one of the best I’ve seen in a
reloading manual: it’s very well organized, easy to read, and covers
topics I’ve picked up over the years, but haven’t seen written down and
organized in one place.
