When do you feel like you have enough ammunition for your gun? I've got about 1000 rds of .223 for the Mini-14, and I plan to pick up at least another 500 soon. I have 600 of .308 for the CETME, and plan to pick up another 200 or 400. I have 300 of .45 and I feel like that's enough. I buy a few boxes every time I go shooting, plus I do a small bulk order every few months or so. What do you guys try to keep on hand? IBfreaks with 20k loaded in magazines at all times.
