Jar,
I'll echo the sentiment about trying to load steel cases. I suppose in a survival situation, and you had nothing else, then of course one does what he has to do. However, we have a whole host of excellent conventional brass for loading components available to us, and you're best served by using them.
When calculating the cost of your handloaded ammo, consider not the initial purchase price of your brass, but the number of times you can load it for your individual gun/load, then figure based upon that the cost per load for your brass.... you'll find it is quite a bargain indeed!
Too, depending upon the caliber you shoot, there are some outstanding buys on once fired brass out there right now. 9MM, .40 S&W, .38 Spcl are so cheap for once fired brass, that it's not even worth looking for a lost piece of brass when you're out shooting, much less taking the chance and having the hassle trying to load steel commie cases!
FWIW,
God Bless,
Marshall
