Short answer is no. Not at 100 and not at 1000 or anywhere in between.

I don’t weight sort bullets at all. Waste of time.This is helpful Bart. I will ask the next question and I think you may have posted the answer somewhere before. What weight difference do you sort for? Do you use the same cutoff for all dostances?
Those who throw and do not weigh do.It all depends what your comfort level is. Me personally, when I set up I want everything to be perfect. Knowing that you have done everything possible is critical for your confidence on the line. Some might say that .30 is nothing to worry about but what if that also includes you powder charge! I am confident in saying that no BR shooter in the country would settle with that.
Those who participate in 600-1000yd Benchrest do not throw. PPC is a completely different. Loading is performed at the range. Everyone brings pre-sorted components.
