Thank God you can still count to 20 with your shoes off. Thanks for having the courage to post up and tell us about your boo boo. That is a good reminder to not circumvent your sound reloading practices. And another reminder to actually look hard at the powder as you are putting it into the powder measure and to make sure your powder measure is empty before you pour the powder in. I make it a habit to turn my measure over upside down or to cycle the powder throw several times before loading it up with powder before reloading. And for sure to never have any other powder cannister out besides the one I am loading with while there is powder in the measure or powder trickler.
