I was a shooting “hobbyist” for many years before I started to become aware of the deteriorating situation. I have a number of firearms, most of which are not good for combat and others of limited use. I believe that ammunition availability is critical. I will stick with my Garand (.30-06), Mini-14 (.223), Bolt action (.308), 1911 (.45 ACP) and a .357 revolver. Ammunition for these might be more available than others should I run low on my own supply. I can work on any of them and have spare parts.
