I haven't been reloading that long so I don't know if it matters much but I've noticed that bullet weight is not very consistent and can be off by up to 10gr within the same box of bullets. All the brands I checked had discrepancies in the weights from bullet to bullet. I checked Barries plated, Xtream, Winchester FMJ, and Hornady. All were about the same. Not a problem for the average shooter? Do you guys that do serious competition shooting weigh bullets to get better consistency?
