Inspection and Measurement
Inspection and measurement improve your shooting accuracy by providing useful data in a continual quest to eliminate variation from your loaded ammunition. Brass cases liquefy in the gun’s chamber when the round is fired; therefore; cases flow and change. Case necks and bullet tensions are just two crucial variables to control in order to maintain consistent accuracy.
Note that when inspecting and measuring during reloading, you may not necessarily follow all of the procedures listed below or even the order shown. As you become more proficient in reloading, you will fine-tune your own process based on your equipment, your rifle calibers and personal preferences. We suggest that you continue to read, learn and understand various methods so that you can find the system that works the best for you.
- Inspections during the Loading Process – We suggest getting all your cases fireformed through your gun before expending much effort inspecting and measuring. Invest in a good dial caliper and learn to have a good “feel” with it. The Forster Datum Dial is great for setting up your dies to fit brass cases to your gun’s chamber.
- Measure the Loaded Ammunition – The Case and Cartridge Inspector is a great tool for checking loaded rounds as well as a variety of other important dimensions.
Safety - Please follow all pertinent safety procedures such as wearing safety glasses, being in a well-lit and well-ventilated workspace, and having all reloading tools in top working condition. Also, no flames, sparks or static electricity.
