Just got my bullets in the mail yesterday, 9mm, 115g, FMJ. Loaded up the first 100 rounds this morning. I was shooting for a OAL of 1.135. About 75% of the 100 came out at that. A dozen or so came out at 1.142 and another dozen at 1.130. Should I be concerned about the difference in lengths? I tweaked the die and got the long ones back down to 1.135 but the short ones I let slide. Is a .012 fluctuation normal for budget brand bulk bullets? Been loading my own cast for years and always been spot on. Just recently got into the FMJ thing.
