Which means there could be a round in the rest of the loaded ammo with a near double charge..
Or best case scenario.. A round simply didnt get charged with powder and the primer just pushed the bullet an inch or so down the barrel where the next round fired normally collided with the stuck bullet and both went on to the target..
Now that you said that im going to take the rest of the bullets apart to make sure there is no double charge thanks for mentioning it.Know matter how much one thinks he knows about guns its amazing how much we dont know.
