550b primer slide sticking,,,,no way to do 500/hr

Easy fix

Don't feel bad. It took me 4 hours to do 100--.308 on my 650 today and that was reloading only. All the prep work with the cases was done last week. I detest the 650!!!!!!

My 550 has been giving me the same problems. I will check the holes to see if I did the same damage. All of my polishing and cleaning sure isn't fixing it. Thanks for advise Tires2burn.

Sig2009. If yourr having problems with your 659 so you only load 25 hr, you either need to call dillon or sell your press. Something is wrong!

I had the same problem. My 550b is about 5 years old and the primer slide was sticking on both small and large primer bars. I tried all the tricks. None worked very well for very long. After around 4 - 5 hundred primers the bar would start to stick open or part way. I decided I was going to make it better or destroy it and start over. I took out the primer bar and went to work with a file. The inside of the primer drop where the bar runs was not even close to square.. I squared everything up and give it about 3 -4 thousands clearance (wiggle room) in the track. No more problems. I have around 15 K through it and just changed over to large primers did the normal cleaning; it was dirty but works like a charm now.

Had the same problem with my 550b recently. Hit it with a little dry silicon spray and it started working again. Ran a couple of hundred primers and the problem has not returned yet. If it comes back, I may give dhenry's solution a try.

I run two 550s, one lp and one sp. They are at least twenty years old. I never have any priming issues unless the two bolts holding the primer assembly are too tight. I use no lube anywhere near the primer assembly and just use an old dry paintbrush once a year or so to clean the slide area.
