I have a swage it that I run on my 650. I run all my 9mm and 556 brass on it when I get a bunch. I have done about 20000 pieces of brass on my 650. The only thing I have had go wrong with my press is the index return spring broke. I replaced it with one out of the spare parts kit. And then about a week later the index cam broke. Looked at it and it looked like it might have been hitting on the press. Dillion sent both parts and have not had anymore problems. I think what happens is that when you take off the primer seater ( the ram with the spring) is that when you do your upstroke to sewage the primer pocket, that it might let the cam hit the bottom of the press. That is what broke it. But like I said Dillion warrants all the parts and I didn’t see any signs of anything on my press.
