I like to go to the range and shoot tin cans, lots of them. It's a real pain in the ---- to have to reload a mag after 5 shots. I would prefer to load 30 rounds and shoot them all before having to remove the mag and reload it. Or take lots of loaded 30 round mags to the range and not have to reload any of them at all. What a waste of time.
And what's wrong with having 30 rounds? I don't really think I'll ever get into a shootout other than with tin cans, so why can't I have 30? My car will go 120 but I don't ever take it above 75.
