I started out in '05 just peening with no bushings. Tony showed me how to use the bushings and I've never looked back. Once you do it you will love that you can literally pound the Crap out of the pivot pin (with in reason) and the clearance remains consistent.
I use a 10 degree reamer and ream about half the hole.
The smoothness of the action depends on the tang shape and the way its finished as much as the pivot.
I hope this helps.
Do you mean you ream about half the depth of the hole?
