I have 100 75 gr. Hornady HPBTM without cannelure. Is there any affect on accuracy with working up the load using these and then switching to the same bullet with cannelure for storage ammo?

None at all in my experience. I've shot the same combos in Hornady 75, Sierra 77, and Nosler 77 with no issues.

No, I have done this and noticed no difference in accuracy.
