NEVER had a round with no powder in it! I double and triple check as the bullet gets seated. Now I have had a case with no primer in place. Powder running out of the primer hole as you pick up the case. (DUH!!)
Any round that FTF gets set aside and as soon as I get home, pulled to see what's going on. Primers are punched out and SMACKED to make sure it's not a primer problem.
