Hardly worth the effort. My reloads run about 25 cents a round (with cheap bullets). So I only save about $10.00 a shooting secession compared to steel cased cartrages. Once a week for 5 months I doubt I save more that $250.00 a year. Now since I bought a Lyman Case Prep Center ($129.00) it takes about 1/2 a second to take out the crimp on a Nato case and those usless 2,000 (5.56) cases (Free) I had gave me about $400.00 in free brass. And since I ues my (cheap) Lee Classic Turret press to load about 100 cases in a hour and a half. It really cuts into my quality time doing all those chores for the little lady. (so I can go out to shoot on the weekend) And since my ammo is about 1,000 percent more accurate and reliable than the junk surplus stuff, I could just go out and buy a 1,000 rounds of surplus for about $285,00 plus Hazmat free and shipping fees. (when on sale and available) Or just go to my closet and grab 2 or 3 or 4 boxes (50 rounds each) anytime (before, during or even after an election) and go and shoot. (now that is priceless).
Hardly worth the effort.
