I have a 550 that I have been using lately for 9mm and want to start 45 and 308 soon. I have seen many posts about people having two 550's. Is the change over that bad or tedious to by a 2nd 550 to have one set up for each primer size? From my expierence which is very limited it doesn't seem to bad to switch over. A deluxe quick change is a $100 and maybe $30-40 for an additional primer assembly for a total of around $140. Another 550 would be about $326, a difference of about $186. I would be buying a deluxe quick change anyways, another 550 would save that. Whats the consensus on this Wanna kill these ads? We can help!
