Limiting ammunition isn’t effective, Limiting magazine capacity on the other hand. I live in Europe where firearms are heavily regulated, yet they don’t care about the amount of ammunition. In fact, you always get a 30% discount if you buy bulk and bulk means per 1000 for quality and per 1400 for surplus. If you have 6 different calibers it adds up quickly. That’s how much they care. There is a limit on the weight of total gunpowder before you need a fireworks storage permit though… there are a lot of gun owners in Europe, but we don’t practice in schools and shopping malls, I don’t know what is wrong with America
