CFE223 is a new powder and hasn't had time to work its way into general load data, so Hodgdon is going to be your data source for now. For the 40 grain Varmageddon use the Hodgdon data for the 40 grain Nosler Ballistic Tip. Just be sure you don't skip beginning with the starting load and working up in no more than 2% increments toward the listed maximum while watching for pressure signs. For the 55 grain Varmageddon, follow the same approach using the Hodgdon data for the 55 grain Speer Spire Point.
If you are looking for accuracy loads, you'll want to use even smaller steps, like 0.2 grain steps.
