I opened a new box of name brand bullets and something about the size made me check the actual weight of the bullet. The box said 140 gr., in fact they were 130 gr. Could have been a real problem if the scenario was reversed and it was140's in a 130 box, especially given the charge I was using. In 55 yrs of reloading this is a first. Makes me wonder if I should check actual weight each time I open a new box.
