For the record, I don't shoot Hornady ammunition, I use Hornady bullets in my handloads. Hornady is pretty darn expensive, and I'm not a rich man...
When I first got my 556, I was testing ammo and did try a few different kinds of Hornady ammo, but it wasn't anything spectacular.
As for that story, I think it sounds like BS. Then again, I think the whole legal system is, to put it lightly, quite flawed.
