I used a 20 round magazine because its easier to take pictures of with everything attached to it, but the process is the same for 30 round magazines.
I can't stress enough firearm safety, and because of that you will notice there are no firearms present in any of my photos. If you play with firearms or ammunition your playing with your life.
Step 1: What your going to need
Step 2: Load the clips
Using the groove on the cartridge as a guide slide all 10 rounds down into the clip.
Step 3: Prepare to load the magazine
Take your first loaded stripper clip and slide it into the loading tool already attached to the magazine.
Step 4: Load you magazine.
Once your last round is inside of the magazine remove the clip. Repeat the process until your magazine is full then remove the tool and your ready to go!
Proper technique may take a magazine or two in order to master, but with a little patience and a little practice you can get really quick at doing this.
