Hi DC it's sad when the old people get dementia, my Mother-in-law got it and she went really downhill.
With the bullets it would be hard to keep track of them because people go out into the bush hunting and they could always say I went hunting but nobody needs an AK-47
The trouble is the criminals will always get a gun and in some countries where there are a lot of guns people want one to protect them selves from the crooks so I think the best thing is to get rid of the semi Automatics and the Automatics and pistols that can be hidden under a coat then people who want to hunt can still hunt with a single shot and people who want to protect them selves can. Also you should be of good character before you get a gun licence. In time if the numbers of guns is reduced then it would make it harder for crooks to get a gun but if they are really determined they will.
