When we attend public shooting ranges, we only waste our time and money. If we really want to use our handguns for home defense, we need regular specific training, including fast shooting from different positions and in different situations. Public shooting ranges never allow you this kind of training due to safety reasons. Even if you have a place for shooting, where you can train this skill, the usage of real bullets is very dangerous because sometimes they could go in any unpredictable directions. Therefore, for this training, wax or rubber/plastic bullets are the optimal solution. I have tested the Teflon bullets and found that they are also dangerous due to their hardness. I would recommend switching to wax bullets – cheapest method to train defense shooting.
On internet sites, there are many posts describing how to make homemade wax bullets for revolvers. These methods are simple; however, wax bullets made by these methods sit completely inside the cases. It creates a problem to feed semi-autos from their magazines (http://www.guns.freaksho.net/articles/waxbullets.html). I used another method, which might be more time consuming but resolved this problem. There are several simple steps:
1. Remove used primers in several cases (5-10)
2. Enlarge primer holes up to 3-5 mm, using a drill.
3. Lubricate inter walls of the cases with any oil to avoid wax adhering
4. Lubricate also any smooth metal surface with oil. I used metal caps.
5. Put the cases on this oiled surface
6. Holding a piece of paraffin wax, melt it by a soldering iron and fill the cases drop by drop.
7. Give time for wax hardening. You can put the cases in water.
8. Take a small stick fitted to drilled holes and push the wax bullets from the cases. As the cases were oiled, the bullets are pushed out easily
9. Repeat steps 3-8
All bullets have some extensions corresponding to drilled holes. This extension prevents the wax bullet to move inside the primed cases. For shooting, I use standard small pistol primers and add in the primed cases a gun powder (~1/5 of 22LR case volume). For this case, I did a small cap from 22 LR case.
