ernie Posted February 20, 2016 Share Posted February 20, 2016 i dont load as much as most members here but i run into a problem. when I use progressive loading, ex 38 special. as long as primers are in the tube. I cannot rotate to change die positions. tried to adjust according to directions, etc. then the conflicting problem is when I prime the cases, the primers don't fully engage all the way in the case. so for all practical purposes I don't have a progressive press. any suggestions would be welcome Link to comment Share on other sites More sharing options...
Vlad Posted February 20, 2016 Share Posted February 20, 2016 When you say in the tube do you mean in the priming cup? The tube really has nothing to do with the shell plate rotation. If I understand you correctly, if there is a primer in the cup, the shell plate doesn't rotate but if there is no primer in the cup the shell plate rotates? And then it also doesn't sit the primers fully? It sounds to me like something is messed up with the primer cup assembly, Call Dillon, they'll probably send you a new one or may have additional ideas for you to try.

Sarge Posted February 20, 2016 Share Posted February 20, 2016 Make 100% sure you gave correct primers and primer assembly mounted to press Link to comment Share on other sites More sharing options...
GrumpyOne Posted February 20, 2016 Share Posted February 20, 2016 For the primers not fully going into the casen you aren't pushing the handle far enough forwars on the priming stroke. It also sounds as if you have the depth of the primer cup off (the primer is not sitting deep enough in the cup). Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 20, 2016 Share Posted February 20, 2016 As Vlad mentioned, call Dillon - your primer system is not working as it should. Link to comment Share on other sites More sharing options...
Youngeyes Posted February 20, 2016 Share Posted February 20, 2016 On the 550,when a primer is in the cup waiting to be put into a case, the ram must be raised slightly to advance the shellplate. When the primer is inserted in the case the shellplate will turn smoothly. Make sure that your shellplate is tight. If it is too loose, the case is not held down and the primer won't fully insert into the pocket. Link to comment Share on other sites More sharing options...
Dirty Rod Posted February 20, 2016 Share Posted February 20, 2016 On the 550,when a primer is in the cup waiting to be put into a case, the ram must be raised slightly to advance the shellplate. When the primer is inserted in the case the shellplate will turn smoothly. Make sure that your shellplate is tight. If it is too loose, the case is not held down and the primer won't fully insert into the pocket. That's what I have seen on both of my 550s. If I back off the bolt on the shellplate about a quarter turn it raises the shellplate up enough so that I can rotate the plate without hitting the primer in the cup but, as mentioned, the primers don't seat as well.

Vlad Posted February 21, 2016 Share Posted February 21, 2016 My 550 shell plate turns fine when there is a primer in the cup. Link to comment Share on other sites More sharing options...

It also springs your handle back to rotate position after seating the primer. Link to comment Share on other sites More sharing options...
dillon Posted February 22, 2016 Share Posted February 22, 2016 If you are attempting to index the 550 shellplate with a primer in the cup, usually the primer anvil sticks up high enough to catch the bottom of the shell plate. If you are loading progressively, then there is never a primer in the cup when the shellplate is rotated. Link to comment Share on other sites More sharing options...
MyWifeShootsBetter Posted April 3, 2016 Share Posted April 3, 2016 (edited) Using a 550b My shell plate rotates with a primer in the cup. Check your fail safe rod tension, it returns the shell plate to the at-rest position. I tried to quote the others above put it wouldn't pick/copy post into mine.

If you are loading progressively, then there is never a primer in the cup when the shellplate is rotated. That's one problem I've never had with my RL550B. Doesn't matter if its setup for LP or SP...maybe it's an issue with LR (since they're taller)? I've not done any LR caliber loading yet. Link to comment Share on other sites More sharing options...
ChemistShooter Posted April 4, 2016 Share Posted April 4, 2016 (edited) If I understand you correctly, your shell pate isn't rotating because primers are being seated high and are catching against the insertion hole when you try to turn the indexing star and stopping the star from turning.I recently had this exact same problem. There are a number of things that can cause this, but in my case it turned out the mounting bolts had worked themselves loose. When I pushed up on the handle to seat a primer, the machine itself would move up the teensiest bit because it wasn't tightly clamped to the table anymore. You can't detect this by wiggling the mount. My mount still felt rock-solid. When I put the wrenches to the bolts, though, I could tell immediately the bolts had come loose.I tightened the bolts back down properly---bang, end of primer-seating problem.Checking the mounting bolts is now part of my pre-loading procedure.
