seating primers

Handle will not depress to seat primers.

Have been using press for over 20,000 rounds.

Anyone else have this problem?

Not sure I follow completely. If you do NOT have a cartridge in the priming position, will it still not lower the base plate so that the priming ram pushes upward?

The handle stops when i have fully lowered the base plate, but will not continue to depress and seat primer. Something is stopping the handle from advancing to push the seater assembly to seat the primer.

With no cartridges in it can you can see whether the priming ram is hitting the disk where the primers are held. From the looks of my 650 there are only three things that can stop the motion of the arm.

1. Ram coming into contact with primer holding disk meaning the disk is out of alignment.

2. The powder dropping linkage has come out of adjustment and the spring is being asked to compress beyond where the coils touch one another and cannot compress farther.

3. The priming ram is coming into contact with the disk that holds the cartridge.
