I think the solution is very simple. We should tax every bullet bought, tax every shot fired, and tax every shell thrown in the trash.
We should also tax progressively…After XXXX rounds of amno fired per year, above which a 20% surcharge is assessed from XXXX to YYYY. And then anything over YYYY is taxed at 40% surcharge per shot.
This will punish heavy amno users (who are more proned to discharging semi-auto to automatic weapons in a reckless way)…
