I’m not talking about making rounds more expensive. I’m talking about literally restricting the number of rounds a person is allowed to buy per year.
If you thought about it for 1 second, you’d realize that for training, you can allow as many rounds as someone wants as long as they’re at an approved shooting range where rounds are closely monitored.
Nobody should be allowed to purchase a firearm without supervised training. Shooting at tin cans in your backyard isn’t proper training.
