First, read the English article below.

Each shotgun shell consists of five basic components, somewhat less complex than the materials available for reloading brass. To reload empty shot shells, you'll need:  Empty hulls, checked for wear Plastic wadding of the appropriate gauge Shot of the desired "shot number" Primers Shotshell powder The only reusable component of the shotgun shell is the plastic shell itself, which is ejected from the shotgun after firing a round. To find reusable hulls, look for signs of wear around the mouth of the shell. They should be relatively uniform, rounded and intact plastic casings to reload.  Hold potential reload hulls up to the light and examine the mouth of each for splits and substantial wear along the crimping. If it's too torn up, you won't be able to use it to properly crimp back down, resulting in a faulty shell. Generally, it's a good idea to throw away shells that have been stepped on or jammed with mud in some way. Shells that come from break-open shotguns that allow you to remove the empty shells directly from the gun are your safest bet. Put them directly into a box or bag to keep them, if you want to reload. When you fit the empty shell into the slot on your reloader, the first step is relatively simple. Pull the lever, and the uncapping pin will remove the spent cap from the empty shell, also resizing the casing to proper specifications. If the shell has warped some in transport, this step should round it back out some. The safest way to make sure that you're reloading your shells to the proper specifications is to consult a trusty reload guide like the Alliant Guide. Included will be a rundown of powder weights, shot types, and primers used in all brands and varieties of shells. If you're planning on reloading regularly, it's essential to invest in one of these guides. Each reloader will work differently, so you might check your owner's manual from your reloading press for a proper guide.  Most reload guides call for Red Dot shotshell powder for use in reloading, of a varying amount.12 ga. shells are...
