OUCH!!! Doin' that has to hurt the pride and pocketbook! Has is written in every book, manuel, etc. on relaoding, paying attention and have NO distractions is a must when reloading. I've known and/or heard of those who can't reload without a bottle or beer at hand, talk on telephone, watch TV, have a dvd movie going, etc. while reloading. Have seen first hand or heard of problems they've had. On the issue of charging with powder, when I do so, I use a case tray holding fifty rds. I always 'eye ball' all the powder charged cases to make sure all are charged and none are double charged. I will intentionally double charge one case (if it will hold it) to see what a double charged case looks like to compare it with a single charged one. With some powders it can be very deceiving. Just have to recharge the case with single charge. Of course I use a single stage RCBS press and dump powder using a hand turned RCBS powder measure, those that use the multi/progressive rigs will have to figure out their own safety checks. Thanks to the guy who had the humility and courage to post his mistake so others can be aware and carefull.
