I've had my 550 up and running for about a year now, probably loaded 2000-2500 rounds on it. I've had priming problems the whole time. I can't seem to get the problems resolved, so I figured I would ask and see if anyone has any ideas to get this thing to run smoothly. The main problem I have is the overall alignment of the priming system. Primer punch will not properly align with the primer pocket in the brass, generally if I jiggle the press handle a bit the case will move around for the system to work, but occasionally the alignment is far enough off that the cup of the primer will catch the edge of the primer pocket and either result in shaving off a small bit of brass, or a crushed/crooked primer. I have had the alignment far enough that the primer punch/holder actually is contacting the base plate of the press, a good 1/4 inch below the shell case. When I correct one problem, I seem to create another. Originally I attempted to correct the problem, thinking that the primer system was walking out of alignment, so I loc-tited the system down. This prevents the problem of the punch hitting the base plate on the press, however it makes it that much harder to get the primer seated without the first issue I mentioned, and jiggling the handle no longer works. I've polished/relieved the sharp edges of the primer punch and holder, no real help. I am stuck operating with the whole priming system snug down, but not tight, and it is a fine line requiring a lot of tweaking. Its really annoying Any Ideas? A much more minor problem I have, is the primer bar slide sticks, over powering the spring, which occasionally results in a round loaded with no primer. Not a bit deal, just a mess. I've tried several lubes, and drop of CLP seems to work best and last the longest, but its messy. What do you all do here?
