Around a month ago I purchased a 550B. It was used but not abused. My original plan was to "flip it. After a few failed attempts I decided to keep it and load .30-30 Winchester. I also decided to send to Dillon for a rebuild. I only have $245.00 in it so the cost of the rebuild ($79.95) & the cost of shipping ($50.00) I'll have $375.00 in a "new" 550!!!! I really didn't need it but what heck, it's "only money"!!!! A guy can't have to many Dillons.
