So I get to travel to Norfolk next week and when I do, my son and I want to do the range trip we didn't get to do this past Friday. The problem is I am down to exactly 5 rounds of .40 S/W commercial ammo. I just got my scale Saturday so I am planning to load up some 40 ammo. The question I had is, how many rounds do you make before you test that particular load? Can I load up 100 and take it to the range ? My previous plan, when I had all the time in the world, was to load up 10 rounds and test just those.
