This finding is confirmed by other recent polling that shows that Americans support measures to keep guns out of the hands of dangerous criminals. According to one poll, 89 percent of respondents support requiring all gun buyers to pass a background check at gun shows, 94 percent support requiring gun owners to alert police if their guns are lost or stolen, and 69 percent support requiring those buying ammunition to pass a criminal background check. Another poll showed 86 percent of respondents supported background checks for every gun buyer"Other recent polling" appears to have been done around the water cooler at the Brady H.Q.
How would you like to pay $10 for a Brady Check before buying a $12 box of ammo? I think this would make bulk purchases vastly more popular. Of course if you buy 1000 rounds of pistol ammo you run the risk of being identified as a terrorist, even after the background check.
