I should have followed the hallowed Handi FAQ's.
I was closing in on a 50gr. Vmax load, around an inch @ 100 yds., but had that nagging feeling it could work better.
I finally, after a year, pulled the stock and hosed the lockworks out with carb cleaner. Added a touch of lube and the result:

Four into .68", three into just over .25"
Lesson learned :shock: Listen to the Handigods :toast: :toast:
Thanks Tim, Mac, Fred, SS and all the others.
