FVA, 30 years. Wow. I've got presses that are older than that by a good bit. And I doubt that your reloading skills are any better or as good as mine. As I posted, I've found depth to make a good load slightly better on occassion but I've never had a load go from a pray and spray to a one holer by adjusting the bullet jump. Maybe I'm a little more careful in my prep before I get to the depth part. I'd suggest you give that a try but from your post, it's apparent you already have all the answers.
