A few years ago Nosler ran a bunch of 120 BT with a blue tip instead of red. They sold them as a special run, but still over half off of new. I called them Blue Meanies. I bought 20 boxes.
They are very consistent on the comparator, varying very little, if at all, from .561”. They shoot great, too. The problem I have (if you can call it that) is that the darn 140 Partitions and 150 ELDX shoot just as well.
