I weight sort my pellets into batches that are separated by .1 grain. The reason I do this is to eliminate a variable, different pellet weights, that I have control over. I know I'm shooting ammunition out of my guns that is good as it can be. I'm mainly a hunter, and consistency in pellet weight is important to me at the longer ranges that I shoot. Eighty plus yard shots are quite common on ground squirrels and prairie dogs. Consistent pellet weight is one of the important criteria for hitting small targets at those ranges.
