There are many incredibly valuable things we learn when we work with wildcat cartridges. Loading with no data, or questionable data, is part of it. Also, learning the minut1ae of determining the very beginning of pressure signs and a zillion other aspects of load development.
BUT THE MOST valuable thing we learn from wildcats is to approach EVERY loading project, even if it is for the common .30-'06, as if it was a wildcat.
When you've gotten to that point, when you use the loading data as a rough guide instead of Gospel ... you have become not only an accomplished handloader, but a safe one.
Blessings,
