Went to Gunsite 223 every day with 13 30 rounders and 4 20 rounders. Reloaded them all every night. I also had 3 dummy rounds that I would mix in for tap-rack-bang practice. It helped with training, because you always had to be concious of what was in your magazine and had to make an effort to continually cycle through magazines.
