After you fire the .22 LR bolt action rifle, save your brass to make these:

Free bullets, which makes your AR15 reloading very cheap. I make those by the tens of thousands, and my only cost of reloading is the primer and powder.

And, I also make my 300 Blackout and 308 Win bullets from scrap 5.7X28 FN brass (as the donor jacket):

I also make 380 auto (100 gr) and 9mm (125 gr, Both from 223 Rem Brass); and .40 (165 gr from 9mm brass); and 44 caliber (various weights from .40 S&W brass); and 45 ACP (230 gr from .40 S&W brass); and 500 S&W Magnum bullets (from 45 ACP small primer brass), all virtually for free. Check out the SWAGING area of the castboolits site for details on how to do this. The tools are expensive, but have paid for themselves many times over at this point. Some guys with machining skills even make their own tooling. The swaging is all done on a modified RCBS Rockchucker (the old model) press. Grade 8 pivot pin for the bottom of a custom ram (1/2-20 threads at the top instead of the normal T-Slot.
