Hmmm... I have to say that preventing felons from owning a firearm for say, 10 years after their release, might not be that horrible. On the other hand, we also make a lot of stupid stuff felonies today, to the point that being a felon has lost a fair amount of it's meaning. By the same token, I don't think that keeping guns out of the hands of those judged incompetent is necessarily unreasonable. Not a problem very often even without a law though, so why have it?
Other reasonable laws - assault, battery, negligent discharge, etc... On shooting inside city limits - sure, it might be safe, but I'll add one more stipend in that your home firing range is still subject to noise ordinances. Better have a well soundproofed range, or be prepared to have to limit your range time to the daytime.
Negligent discharge- same laws apply as any other activity that, due to your being a dumbass, is a clear and present danger to others.
Carrying a weapon, especially a gun, during a criminal act would be considered an aggreviating factor, even if it's not used.
Drunk carrying of a loaded weapon would be treated a bit like DUI before the stupidity of finding people guilty of DUI because they were found asleep in the back seat of the car in the bar's parking lot with the car keys in their pocket.
edit: JerryM, you go a ways further than I do.
No guns in bars - Not a concern to me, I'm more concerned about the alcohol or other inhibiting drugs in your bloodstream. I shouldn't have to disarm if I enter a bar simply to pick up a friend, for example.
No CCW under 21 years of age - I'd kick this down to 18
Current laws governing fully auto - I'd reopen the NFA
Current laws governing silencers - I'd legalize them as a safety device(lowers hearing damage)
No loaded guns on aircraft - Why not? Air Marshals and Military carry loaded all the time.
Convicted felons who have committed violent crimes prohibited from owning or possessing - I'd have a review processes in place for restoration after, say, 10 years.
No guns for illegal aliens - covered under my 'committing a crime' section. Every step they take inside the USA is illegal.
