I have reloaded thousands with mil brass which I attained for nothing. This has been very cost effective for me personally and I continue to do so.
Lately, I purchase a quantity of 308 TULA Ammo from Cheaper than Dirt at a cost of $6.49 per 20. The TULA has perfomed exceptionally well for me and just as good as the domestic stuff. I realize the mention of Russian ammo will bring out the bashers, but for the price, it is great stuff.
