So, we've decapped and resized these 90 some-odd 8x57 Mauser brass. Now we need to clean out the primer pockets. Some folks do this, some do not. I find that it makes the process of re-priming the brass a little easier, and with this little pocket primer tool, it only takes a few minutes to clean and blow out the powder residue build-up.

Once this is completed, we need to take one more precautionary step, one I didn't really cover much in my last video: measuring the case length. As you shoot brass, then reload, then shoot, then reload, etc., you basically start wearing out the brass. Sometimes after several reloads, the brass will start to stretch out, especially around the neck of the brass. This is only natural though, because the neck is where the bullet meets the brass, and it experiences a massive amount of pressure in a very narrow area of thin brass.

Therefore, it's imperative to measure the brass before you continue reloading. One way to do this is with a caliper, especially a digital one that measures down to the .001 of an inch or millimeter. Another way is to use a case length gauge, such as the one I use here from Lee. Most times, these gauges are attached to case trimmer tool, so once again, you can potentially knock out to steps all at once. However, I will say that after nearly 400-500 reloaded rounds, I have only seen a case get so long as to actually need trimming with this tool Nonetheless, the gauge itself is a very fast and easy way to check case lengths.

Hope you enjoy this, stay tuned for part 4 coming up...where we FINALLY get to wash the brass! And enjoy the music, this time AC/DC's "T.N.T."
