Secondly, do you think that is unreasonable amount of ammunition? What kinds of legal limitations would you propose?
For reference, that's about enough ammo for one person for less than an hour of time at a gun range. Any responsible gun owner is going to be at the range with some regularity, and would go through at least that much in one day.
1. People don't just practice at formal ranges. Some have personal property where they practice. There are also competitions and events of all sorts in which copious ammo is needed.
2. You can actually make your own ammo (usually by using used casings from previous ammo)
3. In times of civil unrest (like the riots of 2020) 50 may be nowhere near enough. In high pressure situations it may take a full clip/magazine to take down a single opponent.
4. I am not a hunter, but I somewhat doubt 50 rounds of ammo would be enough for hunting.
5. The vast majority of people with copious ammunition are law abiding citizens, and so this would involve a confiscation and restriction on the behavior of citizens who have not and will never commit such crimes.
6. Considering how poorly we've done and restricting access to weed and other drugs, I see no reason that any such legislation would actually be effective.
2. Good, I'm totally aware of this and aware of the limitations.
3. Show me where people were forced to defend their property by filling someone with bullets in the 2020 (riots, your word). No standard magazine holds 50, so your argument is not in good faith.
4. It's plenty, Hunters worry about noise from shooting, cost (if they are hunting for food), and the environment. They don't fill the forest with lead.
5. Nobody said confiscation, build your stockpiles. This is about selling/reselling.
6. Sure, people feel the same about those; they have a similar risk. (sarcasm)
