I'm new to reloading and have been gathering the necessary equipment to start to reload .40 cal. ammo I'm at the point where I will soon be measuring my powder using the lee powder discs. Now when I weigh my charge on the scale and it reads something like 7.045 or 7.102 or whatever and it calls for just7.0 grains would the extra 10th or hundredth make a big deal? I know ideally 7.0 on the nose would be best because that is what it calls for but how accurate does it need to be and still be safe, I'm afraid if I am over just a bit I could harm myself or do I just need to worry about double charges? Thanks a bunch for all your help I am learning a lot on this forum with all the knowledge everyone has.
