It is not uncommon to find a situation like this where the Max charge in one manual is less than the "Start" charge in another. Same bullet, same OAL, same powder, yet completely different results.
As I said, staying within book data is often time difficult if not impossible. Quickload is certainly not perfect, but neither are the loading manuals.
And this is exactly where I ran into issues. Of my three manuals, the two that had relevant info in them are in a very similar situatioin to as you described. Though I did not see any pressure signs in the cases or primers. I have decided to back off the powder charge, and in this case ignore the lyman data. (Even though the lyman data shows I am well within what is acceptable) Instead I will listen to speer. With the quickload showing near identical velocities, and telling me. "hey, you are pushing the upper limit, watch yourself". I will go ahead and listen to it as well. As it also apparently seems to support what speer is telling me.
I did not know about the quickload program before. First time I had heard of it
