HI All, question from new member here and my apologies is this has been answered else where. please point me to the answer. I think I understand importance of weighting the bullets. (I was shocked to find, that my Hornady 168match bullets have up to 1gn variation, while my SMK 175 are within .2gn of each other) but why should you weight and sort the cases? what does it matter if one case weights bit more? Will that have measurable effect on velocity? I weight cases after they were cleaned, sized and prepped. thanks!
