As a result of a post on another thread, I thought I would post some information that might be valuable for new reloaders:
When ever you get a new die or a new set of dies, TAKE THEM COMPLETELY APART!!!
There are a couple of reasons for this:
1. To make sure all the parts of the die are tight and properly assembled.
A) With resize decapping dies, you want to make sure the decapping pin is tightly screwed onto/into the stem. If it's loose, it may break fairly quickly.
B) Make sure the neck resizing button on bottle neck dies is tight, or you may break off the stem or get other weird effects, depending on the stem construction.
C) For the neck expanding die, if it's a Lyman Type M, you NEED to use red or blue loctite to lock the expander part onto the threaded stem. Failure to do this may result in non-uniform neck expansion.
D) For the seating die, check what shape the bottom of the seating stem is just for your own information. It is set up for round nose ball, hollow points, or other bullet shape? Some die sets come with two seating stems for different bullet noses.
2. The 2nd reason is to familiarize yourself with the parts of the die and how they work. With seating dies you will want to know this, because you may have to clean them when using lubed bullets. In addition, there may be moving parts on the die that you don't initially realize are adjustable, and that will lead to no end of confusion.
