14. RELOADING BASICS
14.1. Clean Brass Is Required Before Reloading
•
There are many methods for cleaning fired brass, but the tried and true method is tumbling brass in a Dillon
Vibratory Tumbler with ground corncob or walnut shell media with 2-3 “caps-full” of Dillon Case Polish. Putting a
"clothes dryer sheet" in with the media helps control dust.
14.2. Lubricating Brass
•
Pistol Brass—pistol brass should be lightly lubricated before sizing even if you are using a carbide size die. The
most effective lubricant for cases is lanolin/isopropyl alcohol-based, as in the Dillon Case Lube PN13733.
•
Lubricate your clean cases by laying the brass flat on their sides in a shallow box or “cookie tray.” Pump three or
four sprays on the cases and shake the box so the cases tumble and roll. Repeat this process one more time making
sure that the lubricant is distributed over the cases. Let the cases dry for about 3-4 minutes before using them.
14.3. Head Space—Case Sizing
•
Headspace is an important reloading parameter. Cartridge headspace is the distance from the case head to the part
of the case on which the cartridge stops moving forward in the chamber. Chamber headspace is the distance from
the breech face to the part of the chamber that stops the case from moving forward. Headspace in its common
usage (head clearance) is the difference between the chamber headspace length and the cartridge headspace length
or the amount of clearance front to back the cartridge has in the chamber. If the cartridge headspace length is too
long for the chamber, action will not close and the firearm will not go into battery. If the cartridge headspace
length is too short for the chamber (too much front-to-back clearance), the primer may not go off, you may get
poor accuracy, stretched brass, short brass life, flattened primers or case head separation.
