I ran across these two videos the other night while looking for bullet reloading information. Knowing how to reload your own ammunition and having all the materials and proper tools to do this after the shit hits the fan can be a great peace of mind.
We have all been experiencing a shortage of ammunition, guns, and reloading supplies here since last fall, with stores finally starting to get their stock back up. This run on the gun stores was based on peoples fears of what might happen, could you even imagine how fast the stores would be cleaned out if something actually did happen. So having you own reloading equipment and all the supplies to reload your own ammunition might be something to think about.
These two videos are of the Dillon 1050 reloading equipment with aftermarket modifications. I realize that the Dillon 1050 is out of the price range of 99% of the people out there, but they do a good job of showing the extreme that you could go to when reloading ammunition.
