I have owned a SDB and 550 which both are great presses. After using my friends 650, I sold the SDB/550 and have a 650 on the way.
If you can afford the 650, that is the route I would go. Why short yourself the ability to load rifle?
35 is high for me, at that price I would expect lunch and no set up or tear down. 20 dollars for a pistol match is my cut off, especially since so many matches around me are 10-15 dollars.
Agree with check the crimp. I had too much of a crimp on my 200gr. lead bullets and experienced keyholing, backed the crimp off to where it just took the flare out and my problem went away.
