Read the manual and follow it to the tee with no substitutions or changes from the published data. Max loads are just that. There is no need to max out on a cartridge. The most accurate reloads are many times in the middle of the powder range. Any changes you make in brass, primers, seating depth and especially powders, can cause dramatic increase in pressures over the formula in the manual. Do not go by what a friend recommends unless it's by the book. And a big one, don't be distracted while your reloading. Follow the instructions step by step and you'll enjoy the hobby for many years to come. Take your time and have fun.
