Great you got it figured out! That's a victory!
A lot of the factory loadings now are excellent, and can be difficult to copy. As a 50 year reloading guy, I remember the first time I shot factory loads that were as accurate as my reloads in 7x57, 7mm Mauser, .275 Rigby, what ever you want to call it.
I was 'sort of' disappointed and pretty happy about it at the same time.
Reloading can be fun and frustrating at the same time.
Wait until the most accurate load you have come up with for a firearm is the dirtiest burning powder you have ever used!
