For 3 years I was satified with my 550 and then it gave me 3 squibs.
I use Unique exclusively for my .45ACP and 357mag.
And one reason I prefer the 550 over the 650 is that w/ the manual advance of the 550, I look down into a charged case to make sure the powder dropped before I advance the cases. If it didn't (and I haven't had the powder measure fail yet), I just have to cycle the press again before seating a primer at station-1. You can't do that w/ the auto-advancing 650.
