Do you have a scale that's accurate within 0.1grains? You might try weighing the remainder of the ammo to see if any of them vary from the average weight by a significant amount (say, 3.5 - 5.0 grains). Use an inertial bullet-puller to pull one cartridge of average weight apart, and weigh the powder charge. Do the same with one that varies far from the average weight. Compare the powder charges. When you contact the ammo factory, your findings may be diagnostic of the overall problem.

You MAY find that there's too much variance among the weights of the individual rounds for a meaningful comparison to be made, but it would take you less than an hour to weigh them with a digital scale. In any case, I'd like to know what you find out, when you talk to Summit.
