The next time you get over to Dillon, (you lucky guy!) pick up the repair kit that RockDoc was talking about. It's not too expensive and it will be handy. Sooner or later you will need a part - two hours after they close on a Friday night. Even if they will replace a part free on Monday, loosing the entire weekend for a 85 cent piece is not fun. After I bought my "spare parts kit", I've not needed one part that was in there.

(I've not broke anything)
Since I'm not as familiar with the SDB as I am the 650, I could not comment and I'm glad you got the answer you needed. On mine, the primer mechanism seems to collect a lot of trash. As soon as I detect any hangup, I pull it apart and clean it out. Seems to always work. Also, if you threw any powder loads into brass without primers, there is a good chance that you now have a powder and grease peanut butter under the shell holder. You can get a lot down there before it starts dragging, but I'd pull the shell holder and check it out since this is new to you too. Again, perhaps this only happens to me on my 650, but I'd bet not.
Good Luck!
