I bought a box of Sierra MatchKings, 69 grain. I was having trouble getting consistent COAL with them, so I measured some bullets and found they vary quite a bit in length and weight. I'm at work now, and can't remember the lengths, but they would vary by several thousands. Oddly, longer bullets don't necessarily weigh more than the shorter ones. Most weighed 68.8 grains. I know people sort out bullets by weight, but does anyone sort by length?
