I bought a box of primed 45-70 brass at a gun show awhile back. I got the box out this weekend and noticed one of the rounds was loaded. No big deal, I just pulled the bullet. To my surprise, there was no powder in the case! I am sure glad I pulled the bullet and did not tried to fire it! I have a hard time using some one else's reloads. I just as soon pull the bullets and start over with my own loads.
