That is the reason that you really need to use the same lot number of cases if you can and weight sort all cases to narrow this problem if you want consistency of accuracy. All cases need to be trimmed to the same length and have the inside of the case primer hole de-burred to get the weight of the batch of cases as close as you can make them. Then weight sort them. Laupa case are expensive but you most likely will not have this problem with them like with those Federal.
