Replaces the steel rub block for smoother action with less drag and resistance.
Now for use with all Dillon XL-650 versions!
Align the block fore or aft to time the indexing of the shell plate.
Barely snug the two mounting bolts so you can still slide the bearing block.
Move your press gently to the priming seating position and visually check alignment.
The primer seating stem should be up and centered in the shell plate slot.
If it is not centered adjust the block fore or aft as needed then tighten the mounting bolts.
Please watch my youtube video for instructions.
The design has recently updated, October 2018. This is the newest and improved version. Compatible with more presses. The older version press does not have an alignment key built into the press. It is a bit more of a challenge to align but it does work (see pictures).
