Bob,
I am tapering off on posting my results. Even if they are not accurate, they seem consistent and I feel comfortable using my data as a guideline.
Below is an updated report on my Reloder 7 tests.
Note the pressures for the .425 dia. Winchester bullets as well as the pressures for the .427 dia shank (.429 forward driving band) for the 43-208A.
I did manage to test a few with slight compression that seem manageable.
I use CCI 300 primers and Starline brass unless noted.

Here is an example of the data I keep in my books. This one is a High Pressure IMR-4227 load.
