Yep. A grain of error can take you well over the top with some loads, especially in small capacity pistol cartridges. And that's just for those UTAH 2007 coins from the Philadelphia mint. As soon as you mix the coins, be it quarters or nickels (I still don't have a large enough sample of dimes to see if they're any different, but I don't see why they would be) it looks like about 4% spread is what you have to accept. If you can keep them all the same year and mint, you might cut that in half, but only if the year isn't so long ago that some have a lot of wear.
