Learn to cast your own. Sure, it is more trouble than buying them, but it beats having none. Give a man a box of bullets and he'll shoot for a day; Teach a man how to fabricate ammo and he'll shoot for a lifetime.
Its not enough that I already reload? This forum is getting to Grizzly Adams. :)
After getting into reloading about a year ago, this is my next step. Casting wouldn't, however, be of much use when it comes to homerolling .223 / 5.56.
OTOH. Corbin sells a neat little swaging setup that'll convert used .22lr brass and lead wire into nice hp bullets. The initial setup is a bit pricey and the process a little labor intensive, but if you can't buy finished bullets...
Pardon me while I excuse myself to scrounge wheel weights and mine the berm at the range. 8^)
I shoot muzzle-loaders - cast all my own bullets.
