...when loading up cast loads with powder that permits a double charge - weight the powder, put it in the case, seat the bullet! I did that with the first 20 I loaded tonight and then thought I'd just run through with charging the next twenty. All of a sudden I realized I was putting powder back in the same row on the block!!! Thank goodness I realized and dumped them, but I would have had a serious problem on my hands at the range tomorrow. I was using Reloder 7 and 4227 in a .30-06 case.
