I have a new .300BO build and purchased 500rds of new Starline brass. My question is after reading about how load performance changes after virgin brass has been fired 1x should I just plan to load all 500 at once with my current load data for a plinking round, and then go back to the drawing board once they have all been fired and start over with new load development? I'm not loading for match accuracy, this is for 0-100yard max functionality. Any advice is appreciated. Thanks
