Dillon Precision XL650 Index Bearing Block by Entirely Crimson

Replaces the steel rub block for smoother action with less drag and resistance.

For the Dillon XL-650 progressive press.
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.

Color anodizing adds some durability and a little extra cost.

Please watch my YouTube video for instructions.

The design has updated, May, 2019. This is the newest and improved version. Compatible with more presses.
